          WHY INACCURATE CENSUS RESULTS HURT AMERICAN CITIZENS

                              ----------

        Subcommittee on the Constitution and Limited Government

                       Committee on the Judiciary

                             Washington, DC

    The Committee met, pursuant to notice, at 10 a.m., in Room 
2141, Rayburn House Office Building, the Hon. Chip Roy [Chair 
of the Subcommittee] presiding.
    Members present: Representatives Roy, Jordan, McClintock, 
Hageman, Hunt, Grothman, Harris, Onder, Gill, Scanlon, Raskin, 
Jayapal, Balint, and Kamlager-Dove.
    Mr. Roy. The Subcommittee will come to order. Without 
objection, the Chair is authorized to declare a recess at any 
time. We welcome everyone to today's hearing on the accuracy of 
the census.
    I will now recognize myself for an opening statement. There 
will be some different conclusions and perspectives as there 
always are, but I do think there are some areas here where we 
can all agree that there are ways to improve the census process 
and I do how we will be able to have conversations along those 
lines where there can be some bipartisan agreement, that there 
are things we might be able to do better for future census 
activities.
    Look, it is one of the Constitution's simplest commands. 
Article 1, Section 2 states that an actual enumeration of the 
American people shall be conducted every 10 years. The 
decennial census of Americans, though it sounds mundane, is a 
core pillar of our democracy. It determines how many people 
represent each State in Congress, how many electoral votes each 
State gets in our Presidential election, informs the drawing of 
district lines for State and Federal offices, and affects how 
much money each State receives from the Federal Government. 
Simply put, it is important that the Census Bureau gets the 
count right, and in 2020, it seems that it failed. Indeed, the 
2020 Census should be called the Sanctuary Census. Just like 
sanctuary jurisdictions, the 2020 Census unconstitutionally put 
illegal aliens ahead of American citizens. Under Section 2 of 
the 14th Amendment, known as the Apportionment Clause, the 
census must count ``the whole number of persons in each 
State.''
    At the time of the amendment's ratification, the term 
persons were understood to refer to only members of the 
American political communities, citizens, and permanent 
resident aliens who have been lawfully admitted to the country. 
Just as the Supreme Court has held that jurisdiction in the 
14th Amendment means, ``not merely subject in some respect or 
degree to the jurisdiction of the United States, but completely 
subject to their political jurisdiction and owing them direct 
and immediate allegiance,'' when determining who is a U.S. 
citizen who is born to illegal alien parents.
    Indeed, the Supreme Court has recognized a similar 
principle, noting that in 1992 the constitutional language 
governing the census contemplates more than mere physical 
presence and some element of allegiance or enduring tide to a 
place. It is unthinkable that the 14th Amendment's Framers 
sought to reward states that harbored illegal aliens with 
additional Congressional representation. Yet, that is exactly 
what happens now.
    After the 2020 Census, States with more illegal aliens 
often because of a conscious policy choice to hamper Federal 
law enforcement and welcome immigration law breakers, get more 
seats in Congress, more electoral votes, and more of your 
Federal tax dollars. A lot of them, in fact. A leading study 
found that if Congressional seats were properly apportioned 
based on the number of citizens, Republican States would gain 
between 10-12 seats in the House of Representatives and votes 
in the Electoral College. That is right. Illegal aliens and 
noncitizens have at last ten seats in the U.S. House of 
Representatives and the Electoral College and that was before 
the Biden Administration policies welcomed ten million illegal 
aliens into our country, during his disastrous four years. How 
many more seats will that give Democrats in the 2030 Census if 
nothing changes?
    The counting of illegal aliens in the census and as part of 
the apportionment base also violates the core constitutional 
principle of one person, one vote. The Supreme Court has 
repeatedly held that State and Federal legislative districts 
must be roughly equal in population so that each citizen's vote 
is roughly equal in power. The 2020 Census undermined this 
principle by counting illegal aliens in the apportionment base. 
Today, a voter in a Congressional district with 730,000 citizen 
residents and 30,000 illegal aliens has a stronger say in the 
election of a representative than a voter in a Congressional 
district with 760,000 citizens and no illegal immigrants. 
Shockingly though, the problems of the 2020 Census did not stop 
there.
    Beyond the manifest unconstitutionality of including the 
illegal aliens, the Census Bureau failed at its simplest task, 
accurately counting the legal population of the United States. 
The Census Bureau's own after-action report found that it 
significantly undercounted the population of six States, five 
of which including my home State of Texas, are predominantly 
Republican. In fact, in addition to Texas losing its seat, 
Florida lost out on two additional seats. Colorado gained a 
seat that it did not deserve and Minnesota and Rhode each 
maintained a Congressional seat that should have been lost. 
Conversely, the Census Bureau found that it over-counted in 
eight States, Seven of which are predominantly Democratic. 
Estimates showed that these errors which were unprecedented in 
the recent history of the census cost Republicans six seats in 
the House, six seats, just from miscounting, and that is on top 
of the 10-12 extra seats Democrats have from counting illegal 
aliens.
    What is more, because the Census Bureau used a technique 
called differential privacy to scramble the data underlying the 
2020 Census, these errors are impossible to correct without an 
entirely new census. We have witnesses here today who can 
explain the technicalities. As our witnesses will highlight, 
the practice of differential privacy was derided by outside 
groups across the political and ideological spectrum, calling 
for the use of it to end. In fact, a 2021 Harvard study on 
differential privacy's effects on redistricting noted that, 
``The DAS has a tendency to transfer population across 
geographies in ways that artificially reduce racial and 
partisan heterogeneity. . . .,'' which makes it impossible to 
follow the principle of one person, one vote, as it is 
currently interpreted by courts and policymakers. Together 
then, the 2020 Sanctuary Census denied Republicans 18 seats in 
the U.S. House, 12 by counting illegal aliens, and another six 
by counting inaccurately. More importantly, it cost law-abiding 
citizens in States across the U.S. their equal say in Congress 
and in the Presidential elections.
    Congress must act to ensure that at the very least that 
illegal aliens are not counted for the purposes of 
apportionment. Let's follow the Constitution. Let's stop 
enabling policies and encourage illegal immigration. Let's stop 
weaponizing the census for political gain and let's find 
bipartisan ways to improve the census and let's understand the 
technicalities that we are going to hear about today that we 
think have bipartisan agreement, create problems in terms of 
the estimating procedures that are used in census, and let's 
put the American people first. The people's house, the 
Electoral College, and all the elections and policies that flow 
from that should be representative of the American people.
    I now recognize the Ranking Member, Ms. Scanlon, for her 
opening statement.
    Ms. Scanlon. Good morning and thank you to all our 
witnesses for being here. I look forward to hearing from you.
    As our Founders recognized, the census is fundamental to 
our democracy playing a critical role not just in governance, 
but in shaping decisions made by organizations and institutions 
across American life. An accurate census is essential for a 
fair distribution of political power here in Congress and for 
the equitable allocation of billions of dollars of Federal 
funds to States and communities including some programs like 
Medicaid, free and reduced school lunches, Head Start, and 
SNAP. Its data is used by businesses and nonprofits to 
determine where and how to operate and by State and local 
governments to decide where to invest in public infrastructure 
like roads and hospitals and schools.
    The census is not just some mathematical equation to 
distribute Congressional seats and taxpayer dollars. It is 
deeply rooted in our Founders' vision of what a government by 
and for the people should be. Alexander Hamilton is on record 
saying during the Constitutional Convention in Philadelphia,

        There can be no truer principle than this--that every 
        individual of the community at large has an equal right to the 
        protection of the government.

    Ultimately, the census is a national snapshot we take every 
10 years that helps us understand and define who we are, how to 
govern, and undermining that process in ways that distort that 
picture will harm all us. That is why Democratic and Republican 
administrations alike have historically tried to protect the 
census from political interference and partisan pressures. This 
President and his MAGA allies are deviating from that 
precedent, once again trying to rig things in their favor. Now, 
these efforts are not new. They began under the first 
administration when they tried to add an unprecedented citizen 
question to the census. This was a blatant attempt by political 
appointees to exclude noncitizens from our count which they 
expected to ``benefit Republicans and non-Hispanic Whites,'' 
and which was ultimately rejected by the Supreme Court. Those 
efforts continued with the development of the Right-wing 
Project 2025 manifesto which, as predicted, has become a 
playbook for the Trump Administration. It devotes a whole 
section to plans to appoint political appointees loyal to the 
White House to lead the census ``to execute a conservative 
agenda'' which includes trying to add a citizenship question 
again, focusing census engagement on conservative groups and 
limiting efforts to engage historically marginalized and under 
counted groups.
    Then, earlier this year, President Trump reinstated a memo 
to the Commerce Department ordering that the census not count 
undocumented immigrants when determining each States' share of 
Congressional seats. We just heard a little bit of that 
rationale which really conflates the idea of who is in this 
country legally, not legally. I mean we constantly hear from 
our colleagues here about illegal aliens not understanding that 
fully 44 percent of immigrants are citizens, that another 26 
percent are legal permanent residents, that another five 
percent are here on visas, so the vast majority of the 
immigrants in our country are, in fact, here legally as opposed 
to the constant refrain we hear from the other side of the 
aisle. At any rate, the Constitution's command is that the 
``whole number of persons be counted.''
    The President has also posted on his social media that he 
wants his administration to start work on a new census and in a 
common theme of this administration, it blatantly ignores the 
fact that the Constitution gives Congress, not the President, 
the authority to conduct the census. Our Constitution's Framers 
understood the importance of having an accurate and 
comprehension population count that is reflected in the fact 
that Article 1, Section 2, Clause 3, the Enumeration Clause, 
mandates that representatives be apportioned among the States 
according to the whole number of persons in each State using an 
actual enumeration.
    Later, the drafters of the 14th Amendment kept this 
phrasing while amending the clause to account for the end of 
slavery, reiterating that a State's representation in Congress 
must be determined by counting the whole number of persons in 
each State. It really could not be clearer, the census must 
count the whole number of persons, not just a subset of 
persons, living in the U.S. The Constitution's drafters could 
have used a narrower term like citizens or voters or something 
else, which they did, for example, in other parts of the 14th 
Amendment, but they purposely used the broader term persons in 
the Apportionment Provision, making it clear that all people 
count, including women, who could not yet vote at the time of 
that drafting, children, indentured servants, who were often 
immigrants, and former slaves, and they rejected proposals that 
would restrict the census to voters.
    Additionally, the requirement of actual enumeration has 
never meant that census takers are only required to count only 
those who they can reach directly or in person. We know that 
the effort to count every person every decade has never been 
perfect and that is why there have been continual improvements 
over time, and that is for a variety of reasons, chief among 
them being that certain populations are difficult for census 
takers to reach. Renters are harder to reach than homeowners. 
Children are particularly tough to reach, especially if they 
are not reading and writing yet. The Constitution does account 
for this. The Supreme Court made clear in Utah v. Evans that 
the Constitution does not specify exactly how the census should 
be counted. As the Court noted in that case, census takers 
implementing our very first count in the late 1700s were only 
required to report the names of household heads which are very 
different from our system now.
    Our Framers knew better than to try and anticipate the 
technology or methodology that America would need to conduct 
the count in the future, one that must capture the hundreds of 
millions of people living in the country today. Instead, the 
constitutional North Star they gave us for the census is simply 
that it be accurate. These on-going efforts to cast doubts 
about the results of the 2020 Census, a census that was 
conducted, I might add, while Donald Trump was President, a 
part of a larger scheme, one MAGA extremists have designed to 
redraw maps mid-decade in a blatant power grab, so that 
Republicans can win more seats in Congress and keep the 
Majority despite the increasing unpopularity of their Project 
2025 agenda. In effect, they are seeking a pregerrymander even 
as they attempt other gerrymanders.
    The ongoing lawsuit in Florida which seeks to overturn the 
2020 Census by challenging some of its counting methodologies 
fits right into this scheme. The suit filed against the Trump 
Administration that is presumably sympathetic to the plaintiffs 
may be just the pretext this administration is looking for to 
push for a census redo. If their efforts succeed, Americans 
will suffer.
    Under counts and other counting errors, particularly hurt 
vulnerable and hard-to-reach populations including young 
children, racial and ethnic minorities, the transient and 
homeless, those in nontraditional housing arrangements, and 
those living in very rural or very dense urban communities. In 
other words, people living in America who patronize its 
businesses, drive on its roads, attend its schools and use its 
essential public services, and people who we need to have 
included in the count. If these lawsuits by plaintiffs get 
their way, and the methods used to account for these 
populations are prohibited or limited, essentially putting the 
Federal Government's head in the sand, will only move farther 
away from, not closer to an accurate and complete count. 
Federal funds will be misdirected. States, local governments, 
businesses, nonprofits, and others will make less-informed 
decisions, inadvertently depriving people of what they need to 
live and thrive in our communities and that is devastating for 
millions.
    Of course, we all want, as the Chair suggests, our census 
picture to be fuller and more accurate. It is what our 
democracy demands, and we should all strive to improve our data 
collection and prevent under counting as we look forward to the 
scheduled, regular 2030 Census. To make that a reality, we 
should be talking about reforms that limit the Executive 
Branch's ability to interfere in the count for political 
purposes or reforms to ensure that the Census Bureau has 
adequate funding and flexibility to do the job right. We should 
not try to curtail or ignore scientific methods which are 
available to complete such a huge undertaking or consider 
changes that make people trust this process less, rather than 
participating in it more.
    The census and its results are too consequential for that, 
so I look forward to hearing our discussion today and I yield 
back.
    Mr. Roy. I thank the Ranking Member, and I will now 
recognize the Ranking Member of the Full Committee, Mr. Raskin.
    Mr. Raskin. Thank you, Mr. Roy. I appreciate it. The call 
for a census in Article 1 of the Constitution plays an 
essential role in our democracy, guaranteeing for centuries 
that there will be an appropriate allocation of House seats and 
districts of equal population within each State.
    President Trump's extraordinary mid-decade partisan 
gerrymander offensive has hit major roadblocks recently in 
California, in Utah, and in Federal Court in Texas, but his 
forces have continued on their path of destruction and are now 
targeting the 2020 Census itself as a way to tear up the 
political map of the country.
    This week, President Trump released this telltale statement 
on social media. This all began with the rigged census he said. 
We must keep the Majority at all costs. Republicans must fight 
back.
    What a syllogism we are offered because Trump must keep the 
Majority at all costs, therefore, the 2020 Census was rigged. 
This is lunacy. It is like saying because Trump had to win the 
2020 election, he really wanted to win it, therefore the 
election was rigged and he won it. That is just derangement.
    The 2020 Census was not rigged. A 2024 report by the 
Government Accountability Office reviewing the accuracy of the 
census found that the accuracy of the 2020 national population 
count was consistent with the previous census. While the 
Bureau's Post-Enumeration Survey estimated significant net 
coverage errors in certain regions and States, the accuracy of 
the count was overall consistent and over counts and under 
counts of the margins are nothing new. The census was not 
rigged.
    The actual institutional weakness of the census, as the GAO 
reported, is the chronic under counts of communities of color 
which persisted through the 2020 Census. In 2020 and 2010, 
``Black or African American and Hispanic persons, young 
children, and renters, were systematically under counted while 
non-Hispanic White persons, adults over 50, and homeowners were 
over counted.'' Are we going to have a hearing planned on that? 
Maybe on the same day we are going to have a hearing with the 
Epstein victims. I do not know.
    The Census Bureau faced unprecedented challenges in 
conducting the 2020 Census because of the raging global 
pandemic and the Government's inadequate response to it. COVID-
19 significantly complicated census activities, many of which 
were suspended or delayed. In many States and localities, 
lockdowns, and travel restrictions stopped the Census Bureau 
from accessing communities entirely. The Bureau also had to 
contend with national disasters in a number of States, as well 
as a planning budget that had been dramatically cut in the 
first Trump Administration. These two are the real problems 
that we should be discussing today. Instead, we seem to be 
wasting our time on a long list of fanciful, self-pleading 
theories that have no basis in law or history, and they fly in 
the plain text of the Constitution.
    Before we assign blame for any actual or imagined 
inaccuracies in the results of the 2020 Census, let it be clear 
that it was the first Trump Administration that was responsible 
for preparing the 2020 Census and the greatest obstacle to an 
accurate 2020 Census count was President Trump himself. He 
repeatedly sought to undermine the accuracy of the count by 
adding a citizenship question which experts warned would 
dramatically depress participation including by American 
citizens and skew the results for Democratic and Republican 
States alike. Thank goodness that the Roberts court thwarted 
that when it found that Trump's process is completely contrary 
to law and the President's pretext for adding the blatantly 
political citizenship question was ``contrived.''
    The Trump Administration told the court that they needed 
citizen questions to help enforce the Voting Rights Act and 
then after oral argument, the evidence came to light indicating 
that the request of the administration, a GOP redistricting 
expert, had provided an analysis showing that the addition of 
the citizenship question to the census and the use of citizen-
only data for redistricting would politically benefit 
Republican and the White community. The Supreme Court found the 
administration's formal excuses completely unbelievable, 
calling them contrived.
    Now, in his second term, Trump and his allies are once 
again seeking to weaponize the census in an unlawful way and 
undermining its accuracy. Trump instructed the Commerce 
Department to exclude undocumented immigrants from the census 
count, a policy that one three-judge panel said, ``has already 
been rejected by the Constitution, the applicable statutes in 
230 years of our history.''
    The Constitution makes clear that the census includes, 
``the whole number of persons in each State to ensure a 
complete picture of who resides in the country.'' As Republican 
Senator Jacob Howard of Michigan stated during his introduction 
of the 14th Amendment in 1866, ``the basis of representation is 
numbers. That is the whole population, numbers, not voters; 
numbers, not property. That is the theory of our 
Constitution.''
    In the face of this overwhelming textural and historical 
evidence telling us that every person must be counted, some 
State officials have filed meritless lawsuits against the 
Commerce Department challenging the constitutionality of the 
Census Bureau's longstanding, constitutionally mandated 
practice to count all persons who reside within the U.S. 
regardless of their citizenship status. Right-wing, MAGA 
activists in Florida have also filed suit against the Commerce 
Department claiming that the census' use of group quarters 
count imputations and differential privacy violated the 
Constitution in the Census Act and called the accuracy of the 
census in this question.
    Do not let the jargon or these tortured arguments fool you. 
The lawsuits are part of a coordinated strategy to give 
coverage to this mid-decade attack on the 2020 Census' 
apportionment count ahead of the midterms. Our democracy and 
our society cannot afford our constitutional census being 
turned into a constant instrument of partisan conflict, 
division, and advantage. Let's reject this dangerous direction.
    Mr. Chair, I yield back to you.
    Mr. Roy. Well, I thank the Ranking Member. Without 
recognizing--Mr. Jordan is not here, without objection all 
other opening statements will be included in the record. We 
will now introduce today's witnesses.
    We will start with Mr. Mayfield. Mr. Mayfield is a member 
at Chalmers, Adams, Backer & Kaufman, where his practice

Advisor at the Center for Renewing America. Wade is a combat 
veteran who served in the United States Marine Corps as an 
infantryman deploying in combat theaters three times in Iraq 
and the Horn of Africa. He has significant experience and 
involvement in campaign activities, conservative grass roots 
movement and the public-policy development and for the record, 
he also served in my office in my first term in Congress as my 
Chief of Staff.

                   STATEMENT OF TREY MAYFIELD

    Mr. Mayfield. Thank you, Chair Roy, Ranking Member Scanlon, 
and the Members of the Committee for inviting me here today to 
discuss issues related to the 2020 Census. My name is Trey 
Mayfield and I served as Counsel to the Director of the Census 
Bureau at the end of the first Trump Administration during 
which time many legal issues concerning the methodology, 
accuracy, and use of the 2020 Census were raised.
    Our Constitution is largely concerned with structuring our 
form of government and placing textural limits on power. The 
decennial census is one of the very few specific exercises of 
power mandated by the Constitution. The census clause is firmly 
lodged in Article 1 of the Constitution. It is, for 
constitutional purposes, a Congressional responsibility. To 
apportion Members of the House of Representatives among the 
several States so that House membership proportionally reflects 
each State's population, Article 1, Section 2, Clause 3 
mandates that there be ``an actual enumeration'' every 10 
years. Section 2 of the 14th Amendment reiterates that 
requirement.
    When interpreting the Constitution, we must look to its 
text, using the commonly understood meaning of the words at the 
time it was ratified in 1788. The Constitution requires the 
actual enumeration. Not surprisingly dictionaries from the time 
demonstrate that enumeration requires an actual counting and 
not just an estimation of numbers. The Founders were well aware 
of the opportunities for fraud to inflate or deflate a given 
State's population to alter representation in the House. For 
that reason, the Federal Government was charged with conducting 
the census and doing so by actually counting, not estimating, 
how many people were living in the United States.
    Since 1790, Congress has consistently reaffirmed in census-
authorizing legislation that statistical adjustments are 
prohibited in determining our national population for 
apportionment purposes. To be sure, since this data is used for 
many purposes other than apportionment including dispersing 
Federal funds to States and localities, obtaining demographic 
data and ascertaining the State of the Nation in such ways as 
the Congress and President deem appropriate. Some kinds of 
statistical adjustment are permissible in performing those 
functions, but not for enumeration.
    Congress has mandated the census ``be as accurate as 
possible'' and banned the use of statistical adjustments for 
enumeration because it ``poses the risk of an inaccurate, 
invalid, and unconstitutional census.'' Within those 
limitations, Congress has delegated responsibility for 
implementing the census to the Secretary of Commerce and the 
Census Bureau. Congress also requires the President to report 
to Congress the total population of the Nation, each State, and 
the number of representatives to which each State is entitled. 
There is no law, however, prohibiting the President from 
reporting additional information to Congress in that report 
such as the number of illegal aliens in the count and what the 
results of the count would be in their absence.
    Congress has also prohibited the release of any census data 
whereby the person who provided the data could be identified. 
Purportedly to meet this requirement, civil servants at the 
Bureau apply the methodology to the 2020 Census called 
differential privacy. It violates the Constitution's actual 
enumeration requirement and the Congressional prohibition on 
the use of such methods. They refused to allow their method to 
be peer reviewed or to disclose the data on which they 
concluded the differential privacy was needed instead of the 
method the Bureau had previously used known as data swapping.
    Using differential privacy altered both the count and the 
characteristics of individuals and households reported at the 
region, district, town, and census block level. In essence, the 
Bureau's reported population moved people around within States. 
For instance, when testing differential privacy using the data 
from the 2010 Census, the population of Port Royal, Virginia 
was artificially increased 87 percent while the population of 
Stony Creek, Virginia, was decreased by 43 percent. In other 
words, differential privacy results in people from larger 
subgroups and geographic units being moved to smaller ones.
    Opposition to differential privacy was unanimous among 
census stakeholders. Every letter the Bureau received from 
outside scientists and statisticians came to the same 
conclusion: Differential privacy is illegal, it is data 
corrupting, and it addresses a nonexistent problem. It was also 
opposed unanimously by governmental actors and interest groups 
for reasons as straight forward that using fake population data 
makes it difficult for governments to carry out core 
responsibilities such as drawing district lines and determining 
where to locate bus stops and schools and how to allocate 
welfare.
    Studies since the 2020 Census have confirmed that this is 
exactly what differential privacy does. It adds fake people 
where they do not live and subtracts real people from where 
they do live. Thus, all the reported enumeration census data 
from 2020 below the State level is false.
    I welcome the Committee's questions.

                   STATEMENT OF JAY RODRIGUEZ

    Mr. Rodriguez. Thank you, Chair Roy, Ranking Member 
Scanlon, and the Members of the Committee.
    I'm an Assistant Attorney General in the Special Litigation 
and Constitutional Issues Division of the Kansas Attorney 
General's Office. In that role, I'm leading a multistate 
Federal lawsuit against the Department of Commerce challenging 
its practice of counting illegal aliens in the census.
    Mr. Roy. Mr. Rodriguez, can you move a little closer to 
your microphone or ensure that it's on?
    Mr. Rodriguez. Sorry. Is that better?
    Mr. Roy. That's better, yes.
    Mr. Rodriguez. OK. When illegal aliens are counted, it 
inflates the count for a few States with high numbers of 
illegal aliens and gives those, those States more political 
power and representation at the expense of States with smaller 
numbers of illegal aliens. That violates the Constitution, 
which requires an actual enumeration of inhabitants to be used 
for apportioning House seats, and it violates the principle of 
equal representation by making votes in some States count less 
than votes in others.
    The census comes out of Article I, Section 2, of the 
Constitution. It requires Congress to conduct an actual 
enumeration to be used in the apportionment of Representatives 
and Electoral College votes, according to the respective 
numbers in each State.
    In the Founding Era, numbers referred to inhabitants, which 
meant someone with a fixed and permanent connection to the 
place and some legitimate tie to the political community. Under 
that definition, illegal aliens are not inhabitants. They're 
present in the U.S. illegally, subject to removal, and their 
residence is, therefore, temporary and contingent. They're not 
bona fide members of the State. They should not be included in 
any enumeration for purposes of apportionment.
    Historically, Congress has delegated its constitutional 
authority over the census to the Secretary of Commerce and to 
the Census Act, and the census is conducted according to the 
rules promulgated by the Secretary.
    Every census and apportionment, including the most recent 
one in 2020, has counted illegal aliens at their usual 
residence, although it's only in the last few decades that the 
scale of illegal immigration has significantly affected 
apportionment.
    In the Supreme Court, there are two broad categories of 
cases that are relevant to these issues. The first concerns 
equal representation or the principle of one person, one vote. 
Starting in the 1960s, the Supreme Court found that debasement 
of votes, or vote dilution, is a justiciable injury, and when 
State voting districts are unequal in population, it means that 
votes in less populous districts count more than votes in more 
populous districts, which violates the Equal Protection Clause 
and the Apportionment Clause. The Court has held that districts 
must be equal in terms of total population, not in terms of the 
number of eligible voters.
    In these cases, the Court set the lower boundary of who 
should be counted. It hasn't set the upper boundary. Even 
though total population we know is more than just eligible 
voters, we don't know that it must include illegal aliens.
    The second category of relevant cases concerns the conduct 
of the census. For example, in Department of Commerce v. New 
York, the Court held that asking a question about citizenship 
was permitted by the Enumeration Clause, given Congress', 
quote, ``unlimited discretion'' to conduct the census, but 
including the question violated the Administrative Procedure 
Act. Without an APA violation, a citizenship question could 
likely be included in the next census if it was produced by a 
reasoned decisionmaking process.
    In Trump v. New York in 2020, the Court heard that 
challenge to a Trump Administration memo which planned to 
exclude illegal aliens from the already completed census to the 
extent feasible. The Court dismissed the case for lack of 
standing, since there was no certainty that anyone would 
actually be removed from the census pursuant to the memo, but 
it did not rule on the legality of excluding illegal aliens 
from an actual enumeration.
    The census cases show that Congress has broad authority 
over what information is collected in the census and that 
counting illegal aliens remains an open question. The Court has 
not said whether the Constitution requires counting illegal 
aliens or prohibits it, or whether Congress has discretion to 
decide one way or the other. The future of the census will be 
decided in the courts and in Congress.
    Thank you.
    [The prepared statement of Mr. Rodriguez follows:]
   [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
    
    Mr. Roy. Thank you, Mr. Rodriguez. I'll now turn to Mr. 
Miller. You have five minutes.

                   STATEMENT OF JOSEPH MILLER

    Mr. Miller. Mr. Chair and the Members of the Subcommittee, 
thank you for inviting me to testify about the serious flaws in 
the 2020 Census caused by the Census Bureau's first-ever use of 
differential privacy.
    Differential privacy is an algorithm that deliberately 
injects noise--in plain English, false data--into census 
results below the State-level data, all the way down to 
individual blocks. It alters racial and household composition, 
changes population counts, and even shifts those fabricated 
numbers to entirely different neighborhoods, cities, or 
counties.
    Census employees will say they are statutorily required to 
protect privacy as justification for choosing differential 
privacy to achieve that goal. Under differential privacy, the 
Bureau insists that State-level totals remain accurate, but 
everything below that level is intentionally distorted. The 
amount of distortion is Top Secret. Only a handful of Bureau 
officials know the true, unaltered numbers. The consequences 
are severe and criticism is bipartisan.
    Harvard data scientists found that differential privacy 
artificially reduces racial and partisan diversity, making it 
impossible to achieve genuine one-person, one-vote equality. 
The Mexican-American Legal Defense and Education Fund and Asian 
Americans Advancing Justice concluded that the data altered by 
this method are too inaccurate to satisfy the Voting Rights Act 
or the equal population requirements for redistricting.
    Rural and low-population areas suffer the greatest 
proportional harm, destroying the partisan makeup of Congress 
and potentially affecting billions in Federal funding. 
Differential privacy also has three fatal structural flaws:
    (1) It renders the count question resolution process 
meaningless. Localities can no longer tell whether a number is 
wrong because of an actual counting error or because the Bureau 
intentionally falsified it.
    (2) It injects distorted data into every State's 
redistricting process, casting doubt on the legitimacy of 
district lines.
    (3) It effectively gives bureaucrats a permanent tool to 
obscure noncitizen and illegal immigrant populations, 
nullifying any future citizenship question and shifting 
political power away from American citizens.
    Some limited analysis suggests an estimated two percent 
movement of numerical population data, but some reporting has 
suggested that upwards of 20 percent movement is allowable. 
Either way, this poses serious constitutional concerns.
    Compounding these problems, the 2020 Census was the most 
inaccurate in modern history. The Bureau's own Post-Enumeration 
Survey admitted statistically significant undercounts in six 
States, mostly Red States--Arkansas, Florida, Illinois, 
Mississippi, Tennessee, and Texas--and overcounts in eight 
States, mostly Blue States--Delaware, Hawaii, Massachusetts, 
Minnesota, New York, Ohio, Rhode Island, and Utah.
    Those errors alone shifted at least six Congressional seats 
and Electoral votes to the wrong States. Those errors all 
benefited Democrats. When you combine known political 
imbalances in the raw count with an opaque algorithm that 
deliberately moves and alters population data, and all those 
problems, coincidentally, mathematically tend to benefit the 
Left, it is reasonable for Americans to conclude that the 2020 
Census was weaponized, if not intentionally, through 
malpractice.
    Public trust in the Census Bureau has been badly damaged as 
a result. Restoring that trust is simple. Congress and the 
current and next administration must correct the errors 
committed by the Census Bureaucracy leading up to the 2020 
Census and permanently prohibit the use of differential 
privacy.
    Differential privacy policy for the purposes of satisfying 
statutory privacy requirements is insufficient as a 
justification. Statutory privacy requirements cannot serve as 
grounds for ignoring the constitutional requirements that flow 
from Census data.
    The 2030 Census returns need to be accurate, transparent, 
and politically neutral, the way the Constitution demands.
    Thank you. I look forward to your questions.
    [The prepared statement of Mr. Miller follows:]
    [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
    
    Mr. Roy. Thank you, Mr. Miller. I'll now turn to Mr. Yang, 
and you have five minutes.

                   STATEMENT OF JOHN C. YANG

    Mr. Yang. Thank you. Good morning. Chair Roy, Ranking 
Member Scanlon, Committee Chair Jordan, and Ranking Member 
Raskin, thank you for inviting me to testify here today.
    My name is John C. Yang. I am the President and Executive 
Director of Asian Americans Advancing Justice, AAJC.
    AAJC is part of a national network that includes 
independent affiliates in Atlanta, Chicago, and Los Angeles, as 
well as 37 community partners in 37 different States, as well 
as the District of Columbia.
    We have served on numerous advisory Committees for the 
Census Bureau, including the most recent 2020 Census Advisory 
Committee. We maintain a permanent Census Program that monitors 
Census policy, educates policymakers, and conducts community 
outreach and education.
    I appreciate this opportunity to testify before all you on 
the importance of the accuracy of the census. An inaccurate 
census hurts everyone in this country. Over $2.2 trillion in 
Federal funding is allocated based on Census data. State and 
local governments decide where to build hospitals, where to 
build schools, how to widen highways, based on the Census data. 
Businesses decide where to put new stores, what inventory to 
include in those new stores, based on demographic data provided 
by the census.
    That's why every administration going back to 1790, whether 
Republican, Democrat, Whig, Federalist, and Democratic-
Republican, has supported policies and supported a budget to 
fund an accurate census.
    Traditionally, ensuring an accurate census has been a 
bipartisan endeavor, and it has been about science and has 
about statistics. Under the Constitution, the census requires 
the counting of the whole number of people. The Supreme Court, 
as well as the text and history of the 14th Amendment, makes 
clear that apportionment is based on total population and not 
subsets.
    Arguments about counts based solely on immigration status 
or eligible voters have been repeatedly rejected by Congress 
and the courts. Any attempt to add a question concerning 
citizenship or immigration status will only make the census 
inaccurate.
    Studies have repeatedly shown that questions such as a 
citizenship question only cause people to decline to 
participate in the census. To be clear, those people are not 
limited to noncitizens, but also include households that 
include both citizens and noncitizens.
    Such inaccuracies will mean that resources would not be 
distributed appropriately throughout the country. It also 
contradicts the Constitution's edict to equal representation 
for all.
    The Census Bureau is committed to producing and 
disseminating objective, credible, and useful statistics to 
support the decisionmaking of governments, businesses, 
philanthropy, and social service organizations.
    Although the total population count of the 2020 Census did 
not see a significant overcount or undercount, we did see that 
specific populations did have undercounts. The 2020 Census 
showed an undercount for children under four of over five 
percent; of rural areas were undercounted by around four 
percent; the Hispanic community was undercounted by over five 
percent; the African American community by around three 
percent; and the American Indian Tribal population by over five 
percent.
    Now, two common reasons exist for undercounts. First, anti-
government sentiment and privacy concerns are causing people to 
resist sharing information with the government. Less than a 
third of the U.S. population have trust in the Federal 
Government.
    Accordingly, the Census Bureau takes its responsibility to 
maintain the confidentiality of the information very, very 
seriously by ensuring that personally identifiable information 
is not shared or distributed to any other government or any 
other agency at any level.
    Now, differential privacy is simply one means for 
accomplishing that confidentiality. Basically, it creates 
statistical noise to mask personally identifiable 
characteristics that could be revealed when census data is 
overlaid with--against other publicly available data. Now, to 
be clear, and everyone has agreed, differential privacy is not 
used at the State level, and therefore, has no effect on 
apportionment.
    The second common reason for undercount is a lack of a 
robust get-out-the-count program, especially for communities 
that are traditionally undercounted or difficult to count. 
States that invest in their census outreach and invest in their 
operations are more likely to have accurate counts when 
compared to States that did not invest in their populations. A 
State's lack of investment in their census, therefore, not only 
results in a potential loss of representation in Congress, but 
also in a loss of resources.
    For example, many experts expected that Alabama would lose 
a Congressional seat in the 2020 Census. The State, however, 
invested in get-out-the-count operations at an early stage, and 
Governor Ivey was very vocal in pushing Alabamians to 
participate. As a result, the State did not lose a seat.
    In conclusion, it is clear that calling it ``all persons,'' 
not just citizens or legal residents, is a constitutional 
requirement that is also critical for determining the 
allocation of Federal funds and for making data based business 
decisions. Rather than seeking to exclude certain classes of 
people from the count, policymakers and the Census Bureau must 
do everything they can to ensure that everyone is counted.
    Thank you again for the opportunity to testify. I look 
forward to questions.
    [The prepared statement of Mr. Yang follows:]
   [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]
    
    Mr. Roy. Thank you for your opening statement, Mr. Yang.
    We will now proceed under the five-minute rule with 
questions. The Chair recognizes the gentleman from North 
Carolina for five minutes.
    Mr. Harris. Thank you very much, Mr. Chair, and thank you 
for holding this hearing on this very important matter.
    Thank you all on the panel for your presence today and for 
your expertise that you bring to the table.
    I want to take just a moment to talk about the importance 
of including a citizenship question in our census. I want to 
come to you, Mr. Miller. Should the census include a 
citizenship question?
    Mr. Miller. Yes, I would argue that it is constitutionally 
mandated in terms of what the census is seeking to produce from 
a constitutional perspective. Knowing citizenship or residency 
status, lawful permanent residence status or otherwise, is 
important in understanding how all the total population fits 
into what you must do with that data.
    Mr. Harris. Thank you. Has the census ever included a 
citizenship question?
    Mr. Miller. That's a good question historically. Anyone--I 
think it has historically but has not recently. They tried to 
get that going last time and ran into APA violation issues. It 
was not included.
    Mr. Harris. A followup to that, because I think it has--and 
why was the question removed? That would be the real question 
here.
    Mr. Miller. Well, are you asking me to speculate? I suspect 
that it was an attempt to try to increase population levels in 
ways that would help certain States, because they're now 
counting illegal immigrants for the purposes of apportionment 
and illegal immigrants and legal immigrants for the purposes of 
redistricting.
    Mr. Harris. OK. What are some of the effects of leaving a 
citizenship question out of the census?
    Mr. Miller. If you don't know accurate citizen status, then 
if your, if your argument is that, constitutionally, you should 
only be creating political districts with those that are here, 
lawful permanent residents and citizens, or just citizens, then 
you need to know that data to create political maps that 
reflect that dataset, if that's your objective.
    Mr. Harris. Sure. The result of our census not only 
controls how Congressional and State districts are drawn, but 
it also directs the flow of Federal dollars. We talk about 
Medicaid, highway funds, education, and SNAP benefits, all use 
population and demographic data, demographic data from the 
census, and to award funds. When we don't distinguish between 
citizens and noncitizens when determining our population, it 
incentivizes States to mass import illegals through sanctuary 
policies.
    We just went through the Big Beautiful Bill or Working 
Families Tax Act, and we made an effort to ensure illegals are 
not accessing welfare programs. I'm worried that, when we allow 
them to be considered for purposes of determining benefit 
formulas, it undermines that purpose.
    Mr. Miller, do you agree that including illegal aliens in 
population totals for Federal programs undermine the recent 
reforms to prohibit illegal aliens from taking benefits away 
from Americans?
    Mr. Miller. Certainly, there's two questions here: Should 
you count them, and then, how should that data be used, and for 
what purposes?
    Certainly, if you are counting illegal aliens and you don't 
know their location, and the location of those illegal aliens, 
because of differential privacy, is being moved around, that 
would have significant impacts on every single Federal funding 
formula, assuming that memorandums of understanding are not 
being properly submitted to the census to ascertain the 
accurate information on ways to disperse those Federal funds.
    Mr. Harris. Agreed. I would submit that, when we allow 
illegal aliens to be counted toward the total population for 
the purpose of determining welfare award numbers, it distorts 
the proper amount that should be given to that community, and 
that, ultimately, puts a further strain on, on the Federal 
budget.
    Mr. Mayfield, let me ask you really quickly in the last 
moment I'm very grateful to be serving in the House of 
Representatives, which is a democratic body, but I worry that 
the errors in the 2020 Census undermine this institution and 
its purposes, which is to represent the American people. Can 
you, Mr. Mayfield, explain how the way in which the 2020 Census 
was conducted undermined the representation of the American 
people?
    Mr. Mayfield. Thank you for that question, Congressman.
    It's important in asking that question to make a 
distinction between two things: The gathering of the data, the 
collection, and the processing of that data.
    The gathering of the data by the census in 2020 was 
exemplary. As your colleague Mr. Raskin pointed out, the COVID 
pandemic made things extremely difficult. There were also 
hurricanes that affected, in particular, Alabama and Louisiana. 
The collection was delayed.
    The collection was tied to the most successful census in 
history. We had a 99.98 household contact rate. I say, ``we''; 
I had nothing to do with that; the Bureau did.
    There were three primary reasons for that success:
    (1) President Trump insisted that the census follow regular 
order and not make shortcuts in the census.
    (2) The Census had done a good job over the previous decade 
implementing technology and cutting out many, many layers of 
needless followup, including using administrative records, such 
as the Postal Service.
    (3) As you may recall, the Census lockdown day was March 
18th. As chance would happen it, Census Day is April 1st. 
Virtually, everyone was in their home. Once they got done 
watching Tiger King, they decided to fill out their census 
forms.
    The problem that the people here have spoken here today 
comes in the Census's data processing. The largest problem was 
differential privacy, which, as several speakers have alluded, 
moves people around.
    In the modeling prior to the census that was done in the 
University of Virginia under a Census contract, it, basically--
I'm summing this up--moved people from urban areas to rural 
areas, where they did not exist. You can all discern from that, 
if that's true, what the political modeling would look like. 
Another major problem in--
    Mr. Roy. Mr. Mayfield, will you wrap this up?
    Mr. Mayfield. Sure.
    Mr. Roy. We're a little over time.
    Mr. Mayfield. Grouped quarters were a problem because 
colleges, in particular, and other large quarters were double-
counted. The Census went back and changed the data to assume 
that people--where they thought they were instead of just where 
they were when they answered the census.
    Mr. Harris. Thank you. I'm out of time, Mr. Chair. I yield 
back.
    Mr. Roy. Thank you, Mr. Mayfield. Thank you to the 
gentleman from North Carolina.
    I'm now going to recognize the gentleman from Maryland, the 
Ranking Member of the Committee, Mr. Raskin.
    Mr. Raskin. Thank you kindly, Mr. Chair.
    Mr. Yang, first, Section 1 of the 14th Amendment states 
that, ``All persons born or naturalized in the United States 
and subject to the jurisdiction thereof, are citizens of the 
United States. . . .'' Then, in Section 2, it says that, 
``Representatives shall be apportioned among the States 
according to their respective numbers, counting the whole 
number of persons in each State. . . .''
    Obviously, the framers of the 14th Amendment understood the 
difference between citizens and persons, and they used 
``citizens'' when they meant citizens; they used ``persons'' 
when they meant persons.
    Doesn't that pretty much settle this bizarrely lingering 
question of whether or not we should be counting all persons or 
just citizens, when we perform the census?
    Mr. Yang. That's absolutely correct. Thank you for that 
question. If you look at the text of the Constitution and the 
14th Amendment, it counts all persons in the State. Frankly, 
some of the history, both of the 14th Amendment and going back 
to the founding of the Constitution, illustrate that they 
wanted to count the entire population and not simply voters, 
not simply landowners. Obviously, at that point, women could 
not vote; obviously, children could not vote. They want to 
include the entire population.
    Frankly, this debate also came up in 1929 during what was 
called the Apportionment Act. That was the only time in 
Congress at the 1920 Census where we did not have 
apportionment. In that debate, part of the debate was whether 
certain people should be counted. During that debate, at the 
end of the debate, everyone decided that it is still based on 
all population, but during that debate, some argued that people 
should not be counted. Specifically, one Representative argued 
that the--a counting, it should count only voters or citizens 
because, otherwise, it would include the thousands of 
unnaturalized aliens.
    Another Representative said that they didn't want to count 
thousands of Mexicans and Oriental aliens, and that those 
people would end up somehow giving extra seats to California in 
that particular case.
    When they talk about Oriental aliens, I will take that 
personally because at that time there was a Chinese Exclusion 
Act, which meant that Chinese were not citizens. Nevertheless, 
during that time, it was settled that it should still be all 
population for purposes of the census.
    Mr. Raskin. Right. Of course, at various points in American 
history, the determination to count just voters would have 
excluded women, Native Americans, today children still, right?
    Will you explain this controversy around differential 
privacy which seems to be a new one? Will you explain what that 
means, what the practice is, and then, what your response is to 
your fellow panelist there, and specifically, to address Mr. 
Mayfield's last point that: I think this is inflating the 
population of rural communities by falsely attributing people 
from urban communities to rural communities, which would seem 
to me to be inflating the numbers in Red districts that--
    Mr. Yang. No. Thank you for asking me for that question. 
Again, the starting point is that differential privacy was not 
used at the State level.
    Mr. Raskin. It is for--
    Mr. Yang. Sure. Differential privacy is, basically, the 
notion that you will inject, some call it, ``statistical 
noise,'' but masking data in the, the census data. Typically, 
you would take a certain piece of data and transfer it to 
another individual, so that you can't identify individual A. 
There's concern with Big Tech now, with big data. Individual A, 
if you have enough information, both from the census and what 
is available on the web you might be able to identify that 
person. ``Oh, that must be so-and-so who lives on this block.''
    The concern was we needed to devise a system that would 
take some of the data, switch it around, so that you can't 
identify that individual. Again, it was not used at the State 
level. Any argument that somehow a State got less seats or a 
State got more seats because of it is just not--
    Mr. Raskin. Where was it used?
    Mr. Yang. It was used certainly at the lower levels, most--
so--
    Mr. Raskin. Do you mean at the county or municipal levels?
    Mr. Yang. Right. At what's called a Census Block level, 
Census Tract level, it was used there. I agree that there could 
be concerns about how you use that, but at the end of the day, 
everyone that's been doing redistricting still uses that data 
that's available. What's it called? PL 90.
    Mr. Raskin. When the Trump Administration administered that 
or implemented that in the 2020 Census, was that the first time 
it was ever used?
    Mr. Yang. Yes, that was the first time that it was ever 
used.
    Mr. Raskin. Uh-hum, OK. Mr. Mayfield, was your point that 
we shouldn't be using that anymore? Even if it doesn't affect 
Congressional reapportionment, it affects local apportionment 
in city council races, county council, things like that?
    Mr. Mayfield. To clarify, Congressman, it affects all 
redistricting within a State. My friend's point is that, if 
Indiana has a population, say, of three million, that's 
probably correct within the, the normal parameters of accuracy. 
How Indiana's nine Congressmen--I apologize if I've got that 
wrong--are allocated is going to be incorrect and down to the 
legislative, district, and town levels. That error will 
permeate within each State below the State level. When he 
refers to ``apportionment,'' he means the number of 
Representatives that are allocated to each State after the 
census.
    Mr. Raskin. With your indulgence, Mr. Chair, if I could 
just ask him to finish this point.
    Why was this differential privacy thing adopted? What 
problem was it addressing, and what would the alternative be to 
the problem of not being able to get in particular people's 
houses if they don't open the door, or whatever?
    Mr. Mayfield. Sure. Well, differential privacy has nothing 
to do with collection. It has to do with ensuring that Section 
9 of Title XIII is adhered to. In that, Congress has prohibited 
the release of personal information based on using the data.
    In other words, we don't release the raw data, the short 
form that everyone fills out. That is very basic. There are 
basically nine questions: Name, phone number, address, racial 
characteristic, your relationship to the household head, and 
your gender. The only real personal information on that is 
name, address, phone number.
    The census has always kept the granular data out of the 
public eye. You can't get census data that's actually 
collected.
    In the past three censuses, 2010, 2020--sorry--2010, 2000, 
and 1990, the Bureau used what's called ``data swapping.'' 
Imagine you have a block. There are five houses on each side of 
the block. Because the smallest unit of data that is publicly 
released is at the block level, the Bureau scrambles that data. 
You don't know if there's a 20-year-old living on this side and 
a young daughter living on this side.
    That was always used. There was never a problem with it. No 
one outside of the people driving differential privacy thought 
there was a problem, and they advocated for continuing to use 
that
method.
    Mr. Roy. I thank the Ranking Member for his question, and 
I'm going to use a little prerogative, because there's some 
technical stuff here, particularly when it's a nonpartisan 
point. I don't mind it going over on either side, because this 
differential privacy is highly complex, and I do think this 
Committee, on a nonpartisan basis, we need to understand it and 
understand it fully. I'll try to allow some of that 
explanation, as necessary, on both sides, where it's 
appropriate.
    With that, I would be recognizing the gentleman from 
California, my friend, Mr. McClintock.
    Mr. McClintock. Thank you. Mr. Rodriguez, if the 14th 
Amendment actually confers automatic citizenship to anyone 
who's born here, as the Democrats contend, it seems to me it 
would have said, ``All persons born or naturalized in the 
United States are citizens of the United States.'' Period. 
That's pretty clear.
    As you know, that's not what it says. It says, ``All 
persons born or naturalized in the United States, and subject 
to the jurisdiction thereof, are citizens of the United States. 
. . .'' What does that mean?
    Mr. Rodriguez. Well, the courts have interpreted ``subject 
to the jurisdiction thereof '' in other contexts for purposes 
of due process or equal protection, and it's certainly been 
broader than naturalized or legal residents. It's still--
    Mr. McClintock. Has the Supreme Court ever rendered a 
decision on whether it applies to those who are illegally in 
this country who have never sworn allegiance to it, and have 
defied its laws to be here in the first place, and under its 
laws, are subject to deportation as soon as encountered?
    Yes, I realize the Ark Decision was rendered 127 years ago, 
but that applied to legal immigrants who accepted the 
jurisdiction in the United States by obeying our immigration 
laws and who had taken up legal permanent residence, subject to 
a treaty ratified by the Senate.
    Mr. Rodriguez. Right. There seems to be no directly on-
point Supreme Court decision that says that the children of 
illegal immigrants are or are not citizens.
    Mr. McClintock. Perhaps we're due to have that at some 
point decided by the Supreme Court or decided by the people 
through constitutional amendment or statute. Am I correct?
    Mr. Rodriguez. It does seem like it will be heard in the 
near future.
    Mr. McClintock. Mr. Mayfield, it seems to me that a census 
is neither science nor statistics. A census is counting real 
people. People have names, dates of birth, addresses, and other 
identifying information. How can it possibly be that we include 
in our census any count without names and such identifying 
characteristics? It seems to me, if you don't have a person, 
they shouldn't be counted in a census of people. How did we 
deviate from this simple principle?
    Mr. Mayfield. If I understand your question, Congressman, 
the first aspect of the census is voluntary compliance with it. 
Every American is required to answer it by law, but the deal 
that Congress has made is that this information will not be 
disclosed. In fact, they cannot even be subpoenaed by a court. 
That's just how tight the information is kept.
    Approximately 67 percent of Americans voluntarily filled 
out the short form, which is: What is your household data as of 
April 1, 2020? For the remaining third of the country, the 
census endeavors to learn that information. It does so--
    Mr. McClintock. You knock on the door. You get a count of 
the people who actually live there. You enter them on the 
Census Register. That's been done since time in memoriam. I'm 
reading now of statistical errors that shifted the--a portion 
of Congressional seats away from Republican States toward 
Democratic States. Now, how can that be if we're actually 
counting real people?
    Mr. Mayfield. It's important to remember, Congressman, that 
several Members have alluded to so-called errors after the 
fact. The Census does what's called the Post-Enumeration 
Survey. That is modeling. That is statistical guess, is what 
it--
    Mr. McClintock. Well, how did we reach a point where we're 
guessing in the census? Either you're a real person or you're 
not. If you're not, you don't belong in the census. If you are, 
we will count you.
    Mr. Mayfield. As Justice Scalia pointed out in Department 
of Commerce v. The House of Representatives, it's imperfect 
science enumeration, but it's better than anything else we've 
got.
    Mr. McClintock. It's not. It's not science; it's a simple 
matter of counting real people.
    Mr. Mayfield. Well, Congressman, there are many people who 
are very hard to reach. For instance, homeless people, which 
the Census works very hard to count. There are people who won't 
allow--
    Mr. McClintock. You work very hard to find them, but if you 
can't find them, you don't make them up. That's not a real 
census. That's guesswork. Mr. Miller, any thoughts?
    Mr. Miller. Yes. It is extremely important that the data 
that is collected, at least the sensitive, Top-Secret version 
of this data, be highly accurate and that we don't just invent 
people. Because former processes have just swapped people. The 
new process literally deconstructs a person and every 
characteristic, and then, just in the aggregate, creates them 
elsewhere in a whole bunch of different profiles all over the 
map. It's a complete mess.
    There's all sorts of constitutional problems with the way 
we've done it that have impacted redistricting, and there are 
some arguments that, if you don't want to count illegal aliens 
for the purposes of apportionment, because your argument is 
that they are not under the political jurisdiction of the 
United States of America at the time of birth, that this would 
impact apportionment because, if you're using differential 
privacy, you may not know--we don't know what they're doing 
with that characteristic data. Is it actually adding up all the 
way to the top accurately or not?
    The biggest problem with all this is we assume it is. It 
may not be impacting apportionment, but it's all Top Secret. We 
don't have eyes on it. We can't verify it. No one can go right 
now and say that, 100 percent, yes, all this data, even the 
characteristic data, let alone the population data, is 
accurate. That's a huge problem.
    Mr. Roy. I thank the gentleman from California. I will now 
recognize the gentlelady from Washington, Ms. Jayapal.
    Ms. Jayapal. Thank you so much, Mr. Chair.
    I think we all agree on the importance of accuracy in our 
census results. I am concerned about some of the actions that 
are being advocated for are actually undermining some of that 
accuracy.
    I want to turn to the citizenship question first and put 
aside the Constitution, which is a strange thing to say in the 
Constitution Subcommittee, but to not necessarily look at what 
the Constitution says, specifically, persons rather than just 
citizens, and actually talk about how adding a citizenship 
question would make the census less accurate.
    I'm going to come to you Mr. Yang because there is a lot of 
data that shows that communities of color, including American 
citizens, have been historically undercounted. This 
undercounting question is directly related to what might happen 
if a citizenship question was added to the census.
    Can you speak to how adding a citizenship question actually 
hurts us in terms of accuracy and increasing undercounting?
    Mr. Yang. Thank you for that question, Representative.
    The bottom line is we want an accurate census. All the 
studies that we have seen, included by the Census Bureau, show 
that the addition of a citizenship question will undermine the 
accuracy of the census, not only for immigrants, but for all 
Americans, because there's a hesitancy about how that data is 
going to be used.
    That was documented, especially and even going up to the 
2020 Census. Even after the Supreme Court decision that said 
that we cannot have a citizenship question, there are still 
people that were concerned about whether that question 
appeared. That is part of the reason why many believe that 
Hispanic Americans were undercounted by over five percent.
    The other thing that we should remember about this, 
actually, there is a citizenship question on what's called the 
long form, that American Community Survey of the census. Now, 
that is a form that contains 50 questions. It has been tested 
in terms of how we can do that in a way that captures the data 
accurately. Again, the bottom line is accuracy.
    Ms. Jayapal. Let me go to the question of undercounting. If 
there is undercounting, substantial undercounting, how does 
that undercount harm American citizens in terms of how the 
census is utilized?
    Mr. Yang. Well, the undercount affects American citizens, 
then, because we will have areas where there's more population 
than was expected, even though the roads are not wide enough, 
even though the schools are not big enough, even though the 
public services are not big enough.
    Let's be clear, right, highways, public services aren't 
dependent on immigrant status. It's dependent on the actual 
residents that live in that community.
    Ms. Jayapal. Give me some of the other reasons, for anyone 
that's listening to this debate and trying to understand it, 
for why noncitizens should be counted. Again, we're clear about 
what the Constitution says, but go ahead.
    Mr. Yang. Right. Again, why noncitizens should be counted 
is because they are part of the entire community that we're 
talking about. First, we break it down in terms of noncitizens. 
Obviously, that would include people that are legal permanent 
residents. That would include people that are refugees. It 
includes a large body that participated in that community, that 
deserves to have a voice in that community, and nevertheless, 
has not yet attained this notion of citizenship.
    Historically, that's been part of the debates that we've 
had, whether it was for the 14th Amendment, the original 
founding of the Constitution, or as I pointed out, in the 1929 
Apportion Act. We've always agreed with the general principle 
that we should represent the entire population and not just a 
small subset of that population.
    Ms. Jayapal. Yes, that it's very real that we have many, 
many mixed-status families in this country. If you insert fear 
into one group of people, that certainly affects the entire 
family's trust in government.
    Mr. Yang. I appreciate that you bring up the notion of 
mixed-status families. What that means is you have a family 
that has some citizens, some noncitizens, maybe even someone 
that is undocumented. In that situation, that citizen in that 
household would not get the services that they would be 
entitled to because of the fact they are not being counted 
correctly.
    Ms. Jayapal. I wanted to go back to differential privacy, 
because, as the Chair knows, this is an issue where we all have 
a lot of concerns about surveillance. I guess I want to 
understand why we would want to eliminate that ability to 
really mask the characteristics, so we can get accurate 
assessments. I wonder if you want to speak to that.
    Mr. Yang. Yes, the bottom line here is, how do we guarantee 
confidentiality for the community, so that the community can 
trust that, when they are responding to the census, their 
identity will not be made public?
    The reason this differential privacy policy was developed 
was because of the advent of big data.
    Ms. Jayapal. Uh-hum.
    Mr. Yang. Now, you are able to get so much more information 
about individuals off the internet.
    Ms. Jayapal. Uh-hum.
    Mr. Yang. That what might have been unidentifiable before 
by simply swapping data at that block level is not going to be 
enough. That is why this was developed. I agree that we all 
have concerns, we've asked questions about how this is 
implemented, and perhaps some fine tuning is appropriate, but 
that is a proper source of inquiry. The notion of disregarding 
it altogether I think would--
    Ms. Jayapal. What would be the fine tuning?
    Mr. Yang. This is where we all need to continue to work 
with the Census Bureau to see what worked and what didn't. The 
Census Bureau, when they said that they were announcing this 
differential privacy policy, among other things, they said 
that, for 95 percent of the jurisdictions, they expect an error 
rate of under five percent. In that context, then you start to 
understand, OK, this data at these levels still should be 
accurate.
    Ms. Jayapal. Uh-hum.
    Mr. Yang. Now, I would agree we need to test that and to 
see where those five percent did not work; what that actually 
looks like. I think that's an appropriate area for inquiry.
    Ms. Jayapal. Great. Thank you. Thank you, Mr. Chair.
    Mr. Roy. I thank the gentlelady for her questions. I will 
now represent--Mr. Onder?
    Mr. Onder. Thank you, Mr. Chair. I couldn't agree more with 
President Trump that we need to restore the integrity of our 
census, and that this begins with refusing to count illegal 
aliens in our census. For too long, sanctuary States have 
openly defied Federal laws and been rewarded with more 
political power, more Congressional seats, and more influence. 
This is unacceptable and it undermines the very foundation of 
equal representation.
    Meanwhile, States like Missouri that I represent, that 
follow and respect the law, have a diluted voice in Washington, 
and not because we have done anything wrong, but because other 
States have chosen to disregard Federal immigration law, and 
they benefit politically by doing so.
    Mr. Rodriguez, doesn't this mean that sanctuary policies, 
if we count illegal aliens in the census, have the effect of 
giving Democrats an unfair advantage in Congress, in the 
Electoral College, and in Federal funding?
    Mr. Rodriguez. To some extent. I don't think it's entirely 
partisan, though. There are Red States like Texas which also 
have disproportionate levels of illegal aliens in their State, 
and they also benefit--
    Mr. Onder. Right.
    Mr. Rodriguez. Sure, California has been the State that has 
benefited most from this policy.
    Mr. Onder. Yes, but Texas does not have a sanctuary State 
policy, of course.
    Mr. Rodriguez. Yes, of course.
    Mr. Onder. If illegal immigrants are excluded from 
apportionment counts, wouldn't we see some shift in political 
power back to States that follow the law?
    Mr. Rodriguez. Yes.
    Mr. Onder. Yes, because census results also determine how, 
literally, trillions of dollars of Federal dollars are 
distributed, are my constituents in Missouri subsidizing 
sanctuary States with large illegal alien populations?
    Mr. Rodriguez. They likely are.
    Mr. Onder. OK.
    Mr. Rodriguez. It's important to note that, under Federal 
law, the Personal Responsibility and Work Organization 
Reconciliation Act of 1996 prohibit illegal aliens from 
receiving Federal benefits. Calculations for Federal benefit 
purposes that are based on illegal alien populations are wrong 
under the law.
    Mr. Onder. Right. Again, we know that, looking back on the 
2020 Census, it is clear the Census Bureau has admitted that 
there were errors in States, in the counting of States, and 
five of the six States that were undercounted were Red States 
and seven of the eight States that were overcounted were Blue 
or swing States.
    Mr. Miller, can you explain how these inaccuracies in the 
2020 Census occurred and what can be done differently in the 
2030 Census?
    Mr. Miller. The Census Bureau would argue that these were 
difficulties that they encountered due to COVID, and that this 
was kind of a historical unprecedented event that occurred 
during a census, at least in modern times, that I'm aware of.
    Mr. Onder. Excuse me if I interrupt. It seems like 
everything is blamed on COVID.
    Mr. Miller. Right.
    Mr. Onder. Supply chains are blamed on COVID; educational/
lack of educational is blamed on COVID; workforce, COVID.
    What specifically--how did fighting this virus lead to 
these inaccuracies?
    Mr. Miller. Well, that's why it just doesn't make much 
sense to me, because the States that were undercounted were, 
generally, more open than the States--
    Mr. Onder. Where people wearing gloves and masks and not 
able to be out properly?
    Mr. Miller. Right.
    Mr. Onder. I don't know.
    Mr. Miller. Yes, the States that were overcounted were the 
ones that were locked-down and closed, more so, I just don't 
understand the whole COVID logic. I'll take them at their word, 
but it's certainly a strange outcome.
    Mr. Onder. Yes. Maybe everyone at the Census Bureau working 
from home and not actually out counting persons.
    Do we really know the full extent, Mr. Miller, of the 2020 
Census, the census inaccuracies? If they admit to this, is--
    Mr. Miller. No, they have admitted to major miscounts.
    Mr. Onder. Yes.
    Mr. Miller. We do not know the extent to which differential 
privacy has had an impact, because the TIGER file that all this 
exists at the Census Bureau is Top Secret. Only a few people 
have access to it. This is an oversight problem that we really 
need to get some data statisticians in there to really analyze, 
with clearance, to analyze the impacts. Because whether it's 
urban to rural or rural to urban, there has been a lot of 
population movement, and I've seen studies arguing both sides 
of this. There are big problems with this on a variety of 
fronts.
    Mr. Onder. Again, remind us what's the alternative to the 
differential privacy scheme?
    Mr. Miller. Well, there can be a lot of these. IFMS has a 
really good analysis on how to address this. Past practices 
have used swapping, limited swapping.
    Mr. Onder. Right.
    Mr. Miller. One solution is just turn off characteristic 
data until you get to a statistically significant level--
    Mr. Onder. Level where you can--
    Mr. Miller. --of numerical data available, but turn off all 
the characteristic data until you're up at the census tract or 
county level. That way, it's really hard to reverse-engineer 
the algorithm with population numbers that are strong.
    Mr. Onder. It makes perfect sense. Thank you so much. I 
yield back.
    Mr. Roy. I thank the gentleman.
    I will now represent the gentlelady from Vermont.
    Ms. Balint. Thank you, Mr. Chair. Thank you to the 
witnesses. I appreciate your time.
    This is a hearing about the census, so, essentially, a 
hearing about counting people, or put another way, determining 
who counts and who doesn't.
    President Trump has made clear that he feels that 
birthright citizens is not constitutional. He feels that 
noncitizens should not be counted in the census. He has made 
clear that he views the 2020 Census as illegitimate.
    The truth is the President can feel any way he wants; the 
courts have spoken. Birthright citizenship is the law of the 
land. The census counts for everyone, and the 2020 Census was 
as accurate as the 2010 Census.
    Here we are again in a hearing to make these claims, these 
nonsensical legal theories more legitimate by holding hearings 
about this. More broadly, this hearing props up baseless legal 
theories that undermine the census and threaten our 
representative democracy.
    I want to associate myself with the remarks of my 
Democratic colleagues. I would like to take my time to go in a 
little bit different direction here. I want to spend my time 
getting to the heart of this question of who counts and who 
doesn't count in the eyes of this administration. Who is seen 
as a real American and who is not?
    Investigative report by ProPublica has found that more than 
170 American citizens have been detained by immigration agents. 
They've been dragged; they've been kicked; and they have been 
detained for days at a time. These are U.S. citizens. They are 
our fellow Americans. Top Trump Administration officials keep 
denying that U.S. citizens have been arrested or detained at 
all in the immigration raids that are taking place across this 
country.
    Department of Homeland Security Secretary Kristi Noem has 
repeatedly falsely claimed that no American citizens have been 
arrested or detained. There are two reasons that we have that 
she could be doing this:
    (1) That she is blatantly lying to the press. That is one 
option.
    (2) That she doesn't know what is happening under her own 
leadership.
    Either option is deeply disturbing to me.
    We have so much evidence that what Noem has been saying 
about this is untrue. Many news outlets have confirmed these 
arrests and have spoken directly to U.S. citizens who have been 
arrested or detained by immigration agents. They have gathered 
these disturbing stories about how our own citizens are being 
treated by this administration. We have the evidence.
    There's the case of American citizen George Retes, an Army 
veteran who was pulled out of his car by Federal agents who 
were raiding a farm North of Los Angeles. In his words,

        They sat me down on the dirt with my hands zip-tied behind my 
        back. I told them I was a citizen. I told them I had an ID. 
        They didn't care. They never asked me for it.

    This U.S. citizen was held for three days before finally 
being released. He was never charged with a crime. He's just 
one of many U.S. citizens that we can document who have been 
detained or arrested. Again, we have the proof. Secretary Noem 
continues to spread false information.
    Then, there's the case of Jason Brian Gavidia. Jason is a 
U.S. citizen who worked at a tow truck yard when Border Patrol 
agents stormed in. Jason was handcuffed, as he pleaded with the 
agents. He said, ``Let me show you my ID. Let me prove my 
status.'' He said, ``They didn't care. All they cared about was 
the fact that I was Brown and I was in the wrong place at the 
wrong time.'' That's not right. We're in America. That's not 
right.
    The point is that the only people who seem to count as 
Americans to this administration are the people who look 
American. Any of us sitting here in this room, regardless of 
party, would be shocked, would be outraged, would express 
righteous indignation if we were detained based on our physical 
appearance or on our profile alone. Regardless of what we 
believe about this President, I would hope that we would agree 
we would howl at our due process rights being denied.
    Mr. Raskin. Well, would the gentlelady yield for a quick 
question?
    Ms. Balint. I will. I will.
    Mr. Raskin. What does it mean to ``look like an American'' 
in 2025?
    Ms. Balint. Yes, thank you very much. It seems clear to me 
that looking like an American is somebody who does not have 
Brown or Black skin, and sounding like an American is someone 
who does not have an accent. That seems like that's been 
established.
    I just want to end with this: There is nothing more 
important than a person's liberty, nothing. I would hope that 
we can all agree on that.
    We should all be standing up to our government when it is 
arresting and detaining citizens illegally and then lying about 
it. Citizenship in this country is not based on the color of 
your skin; it is not based on the accent that you have. Based 
on the actions of this administration, I'm not confident that 
it believes this, and I find this deeply chilling.
    Before I yield back, I have several unanimous consents that 
I would like to enter into the record.
    First, ProPublica, ``Immigration Agents Have Held More Than 
170 Americans Against Their Will.''
    Second, ``NPR Fact Checks Kristi Noem on ICE Detaining U.S. 
Citizens.''
    Third, an article in The Journal of Policy Analysis and 
Management, ``Citizenship Question Effects on Household Survey 
Responses.''
    Fourth, an October 2015 report by The Congressional 
Research Service entitled, ``Apportioning Seats in the U.S. 
House of Representatives Using a 2013 Estimated Population,'' 
concluding that excluding noncitizens for apportionment 
purposes likely requires a Constitutional Amendment.
    I yield back.
    Mr. Roy. Without objection, those will be entered into the 
record. I will now recognize the Chair of the Judiciary 
Committee, Mr. Jordan.
    Chair Jordan. Thank you, Mr. Chair. Mr. Mayfield, we've 
asked about it before, haven't we? We've asked the citizenship 
question on this census before, haven't we?
    Mr. Mayfield. That's correct, Congressman, many--
    Chair Jordan. From 1820-1950, we asked that question. 
That's 130 years. From 1970-2000, another 30 years. One hundred 
fifty years, we asked the question.
    Mr. Mayfield. That's correct.
    Chair Jordan. The previous speaker just said, if we ask the 
citizenship question, it's going to threaten democracy. Well, 
it didn't hurt democracy for 150 years. In fact, I would bet if 
you--I'll use my--I'll just our district. You can go to Urbana, 
Ohio, our hometown. I bet if I went to Urbana, Ohio; I walked 
to the post office--or walked anywhere, any store. I walk in. I 
see someone I know:

          Chair Jordan. ``Mr. Smith, do you think on the census--you 
        know what the census is, of course?''

          Mr. Smith. ``Oh, sure. Every 10--every so often, we find out 
        how many--we count the number of people in the country.''

          Chair Jordan. ``Mr. Smith, do you think, when we're counting 
        the number of people in this country, it's appropriate to find 
        out how many are citizens?''

What do you think he would say? What do you think the average 
person would say?
    Mr. Mayfield. I suspect the answer would be, ``Yes, sir.''
    Chair Jordan. It would not only be yes; they would say, 
``Well, aren't you already doing that? That's pretty stupid if 
you're not.''
    That's where the American people are. Everyone's for 
counting it. We did it for 150 years of our 250 years as a 
country--or since we declared independence, 249 years, almost 
250 years now. We've done it for most of our history. Everyone 
thinks we're doing it. Everyone thinks we should do it, except 
Democrats in Congress.
    It was interesting, too, in Mr. Yang's testimony, he said, 
``Oh, if we ask the question, we'll get inaccurate counts.'' 
Then, he went on for the rest of his five minutes and talked 
about all the inaccuracies in the recent censuses where we're 
not asking it--undercounts, overcounts, rural America, Hispanic 
Americans, pointing out all the problems, and we're not asking 
the question.
    Somehow, if we ask it, oh, it might get worse because we 
have some study. He even said, people thought it might be on 
the census questionnaire, and it wasn't, and that hurt the 
count--which makes no sense to me. It wasn't a question.
    Think this is so darn simple. Count the persons. That's 
what the Constitution says. Count the number of people, and 
while you're doing that, find out how many are citizens. What's 
wrong with that? It might actually help policymakers when we're 
determining policy if we know those two numbers. That's all we 
need to focus on.
    I'll go to Mr. Miller, if he's got any comments about what 
I commented on.
    Mr. Miller. On the last part, I absolutely agree. There is 
some question on who to count. I think that this, if you get 
into it technically, answer is you can count everyone. You just 
need to know certain population numerical data, then, residency 
status, because that could bleed into policy questions later. 
That that's an important distinction to know, that you can use 
different datasets within the totality of that data for 
different purposes.
    Chair Jordan. Of course, that's useful information for 
policymakers. That's why we do it that way. I get that.
    Let me ask you this question, Mr. Miller: Do you think 
asking a citizenship question on the census is any way a threat 
to democracy?
    Mr. Miller. I do not. I think it's constitutionally 
mandated if you really--
    Chair Jordan. Mr. Rodriguez, do you think, as a 
constitutional scholar here, do you think that's somehow a 
threat to democracy if we ask how many people are here and how 
many citizens are here?
    Mr. Rodriguez. No, it's entirely consistent with 
Congress'--
    Chair Jordan. Mr. Mayfield, do you think that's a threat to 
democracy?
    Mr. Mayfield. The census has no effect on democracy, 
Congressman.
    Chair Jordan. Exactly. Mr. Yang, do you think asking a 
citizenship question, while you say it might impact the 
accuracy--I don't know that I'd agree with that. I, frankly, 
disagree. Do you think that might threaten democracy in some 
manner?
    Mr. Yang. It's a threat to accuracy, which means that it 
would be a threat to how we allocate funds in the United 
States. That's how--
    Chair Jordan. That's not what I asked you. I said, ``Do you 
think it's a threat to democracy?'' because that's what my 
Democrat colleague said just four minutes ago.
    Mr. Yang. How people are being represented, and the funding 
that they get, would be a threat, yes.
    Chair Jordan. You think asking a citizenship--the Democrat 
witness thinks asking a citizenship question on the census is a 
threat to democracy. Do you think that's true?
    Mr. Yang. As currently constituted, it could be, yes.
    Chair Jordan. Well, that's amazing. That's amazing. Finding 
out the number of people and the number of citizens in our 
country is somehow a threat to democracy, that's what the 
Democrat witness said in the House Judiciary Subcommittee 
hearing on the Constitution. That is amazing.
    Mr. Chair, I yield back.
    Mr. Roy. I thank the Chair of the Judiciary Committee. I 
will now represent--the gentlelady from California?
    Ms. Kamlager-Dove. Thank you, Mr. Chair.
    Apologies if this question has already been asked, but I 
like to hear things with my own ears. Mr. Yang, what is the 
census sort of used for? Why do we conduct this onerous 
process?
    Mr. Yang. The principal use for the census is twofold. 
First, is for the apportionment of, Congress, seats in 
Congress, and second, again, accurate count of the population. 
When we're distributing funds, whether it's $2.2 trillion in 
Federal funds or State and local funds, that we're distributing 
the right way. What that means, literally, is where roads are 
built; where schools are built; what services are needed in 
different communities. For businesses, what that means is what 
stores get built and what you stock on those shelves of those 
stores.
    I live in Fairfax County. The fact that our Costco has 
approximately seven different, seven different types of rice is 
a reflection of the fact that Fairfax County is about 20 
percent Asian American.
    Ms. Kamlager-Dove. Uh-hum. Thank you for that.
    I would agree with that, right? Someone who lives in a 
city, a county, and a State, we're always fighting to get the 
resources that we need. It's important to know how many people, 
regardless of where they come from, regardless of who they are, 
what they look like, right, what language they speak, what rice 
they like, it's important to know how many people are in a 
place, so how many hospitals to have; how many schools to have; 
and how many parks to have.
    Am I missing something here?
    Mr. Yang. No. It is as a very basic as that. Again, the 
point is to get an accurate count.
    One of the things that we've been talking about here is, so 
what affects accuracy? We've talked specifically about Texas 
and Florida as being inaccurate counts. Well, I would point out 
that, in the case of Florida, the Federal--the State government 
only allocates $300,000 to the count for the entire State 
compared to the State of Alabama, a much smaller State, which 
allocated $1.2 million to the count of their residents.
    How you do your get-out-the-count operations will translate 
into how accurate the results will be. There is a correlation 
there.
    Ms. Kamlager-Dove. I do understand that it seems like my 
Republican colleagues want to get rid of every single foreign-
born person in this country. It boggles the mind because--
    Ms. Hageman. I would object. I think that this is 
attacking--
    Ms. Kamlager-Dove. It's--
    Ms. Hageman. I think that is attacking individuals--
    Ms. Kamlager-Dove. Well, you've been taking my time. I'd 
like to have my time--
    Ms. Hageman. I think that is attacking individuals--
    Ms. Kamlager-Dove. Point of order.
    Mr. Raskin. Mr. Chair, could you restore the order, if you 
will?
    Mr. Roy. Well, does the gentlelady have--
    Ms. Kamlager-Dove. I made an opinion. I can have an 
opinion.
    Mr. Roy. Is the gentlelady asking to strike--
    Ms. Hageman. I am. I'm asking to strike those words, 
accusing us of that level of racism.
    Ms. Kamlager-Dove. It's not racist. If you think it--it's 
my opinion. I have a right to have an opinion.
    Mr. Roy. We'll suspend for one second. Will the gentlelady 
express the specific words you're asking to be--
    Ms. Hageman. Specifically, what she stated was that the 
people on the other side wanted all foreign people to be 
removed from the country, and that's absolutely untrue.
    Ms. Kamlager-Dove. As I mentioned, Mr. Chair it is my 
opinion.
    Ms. Hageman. That is attacking every person on this side of 
the aisle.
    Ms. Kamlager-Dove. I have a right to my opinion. I said, 
``I believe''--
    Ms. Hageman. I am tired of all the allegations of racism.
    Mr. Roy. Order. Order.
    Mr. Raskin. Mr. Chair, that's not--
    Mr. Roy. Order. Let me suspend for a second.
    Ms. Kamlager-Dove. I didn't use race at all.
    Mr. Roy. Let me suspend for one moment.
    Mr. Raskin. Mr. Chair, if I could, that's not engaging in 
personalities. It's not an ad hominem attack.
    Ms. Hageman. Yes, it is.
    Mr. Raskin. If she disagrees, she can use her own time to 
explain why she disagrees.
    Mr. Roy. Everyone suspend for one moment.
    [Pause.]
    Mr. Roy. The gentlelady from Wyoming, are you withdrawing 
the request to strike the words from the gentlelady from 
California?
    Ms. Hageman. Yes. Yes. I just wanted to point out the 
allegations are absolutely unsubstantiated and it is ridiculous 
to--
    Mr. Roy. OK. I'd yield--
    Mr. Raskin. Mr. Chair, could you instruct her to point it 
out on her own time?
    Mr. Roy. Reclaiming the time, but, the gentlelady from the 
California, please proceed. We will restore the clock.
    Ms. Kamlager-Dove. Thank you, Mr. Chair. I guess I don't 
want to use my own time saying, but I guess now perspectives 
and opinions are no longer important here in this Committee. 
That seems like it would be a shame.
    Mr. Yang, we are talking about the census, and the question 
is--it kind of doesn't matter where you come from. If you are 
someplace, if you are using resources, it would be important 
for that jurisdiction, for that municipality to know that you 
are there. Where I come from, if you get sick, you should go to 
the hospital. The hospital is not supposed to say, well, who 
are you? Let me see all your paperwork. That doctors take a 
Hippocratic Oath to help anyone who is coming in bleeding who 
would be wanting to need or use the resources that are 
available to them in that hospital. Do you understand sort of 
question that I am asking about why it is important just to 
know who is in a particular place?
    Mr. Yang. That's absolutely right. With respect to public 
services and with respect to roads, that immigration status 
does not matter when it comes to the need for good roads and 
the need for good public services. Making sure we have an 
accurate count of our entire population--and again, if you even 
go to Supreme Court precedent in Evenwel, they recognize that 
you should be doing total population counts, whole population 
counts for purposes of apportionment. The history of this has 
been very clear that the census is designed to count the entire 
population.
    Ms. Kamlager-Dove. Thank you for that. As I look at all my 
questions, not one word in any of these questions is the word 
race. Mr. Yang, Assistant Attorney General Rodriguez says in 
his written testimony that apportionment should not account for 
those in a State unlawfully. What would be your response to 
that?
    Mr. Yang. Well, I don't see anything in the Constitution 
that makes any sort of distinction. Rather, what the 14th 
Amendment provides in the census--in terms of apportionment in 
Article 1, Section 2, with respect to census is the counting of 
whole persons, and it makes no distinction.
    Now, in the written testimony it makes reference to the 
fact that somehow they should be part of a political community, 
but the notion of political community does not exist anywhere 
in the text of the Constitution, the 14th Amendment, or the 
Apportionment Act. Certainly, even the contemporary 
dictionaries that he cited, except for a reference of parish 
law, did not make any reference of being part of a political 
community. Rather, simply, a resident is someone that has a 
normal place of domicile.
    Now, to be clear, there are rules that the census with 
respect to people that are transient, with respect to people 
that have tourist visas, for example, should not be counted in 
the census. There are residency rules with respect to census as 
to what is considered a resident.
    Ms. Kamlager-Dove. You mentioned whole person in the--I see 
the constitutional framers use the phrase whole number of 
persons rather than citizen or voter. Why do you think they did 
that? Because of course when you say whole person, of course, 
this time I am going to use race, but I am going to talk about 
myself. There used to be a time when a Black person was not 
even considered a whole person. It was like three-fifths of a 
person. I am getting a little triggered by that phrase. Can you 
explain sort of why the framers used that phrase?
    Mr. Yang. You're correct, representative. Unfortunately, 
when the Constitution was first adopted slaves were not 
considered citizens--for purposes of a census was considered 
three-fifths of a person, as a distinguish from a so-called 
whole person. It wasn't until the 14th Amendment that 
citizenship was given to slaves and anyone born of slaves, and 
that making clear that when we are counting, we are still 
counting all persons in the State.
    Ms. Kamlager-Dove. Tell me again, can you reiterate for the 
folks that can't seem to maybe hear what you are saying about 
why it is important to have an accurate count when you were 
doing the census?
    Mr. Yang. Well, having an accurate count for persons of 
data allows us to make sure that we have the services that we 
need in the United States for everyone. We need a society that 
has infrastructure for everyone. It is true for immigrants, 
nonimmigrants alike. Certainly, there can be policy debates 
around different aspects of that but at least having the set 
accurate data that all us can work from is critical to how this 
Nation functions.
    Ms. Kamlager-Dove. Thank you, Mr. Yang. Mr. Chair, I yield 
back.
    Mr. Roy. I thank the gentlelady from California. I will now 
recognize the gentlelady from Wyoming.
    Ms. Hageman. Well, first, I disagree with the idea that 
there is a constitutional requirement for conducting a census, 
so that we can have different varieties of rice at Costco. I 
almost want to say that almost all countries conduct a census.
    Ms. Kamlager-Dove. Mr. Chair, that is racist.
    Mr. Roy. Does the gentlelady have a--
    Ms. Kamlager-Dove. Yes, that should be stricken.
    Mr. Roy. Does the gentlelady from Wyoming have a response?
    Ms. Hageman. Rice, or hamburger, or any other foodstuff. 
That isn't why we conduct a consensus.
    Mr. Raskin. Mr. Chair, those words, as ill-advised and 
foolish as they were, were probably not engaging in 
personalities, we can let that go and call it even after--
    Ms. Kamlager-Dove. Yes, Mr. Chair, I will withdraw.
    Mr. Roy. Proceed.
    Ms. Hageman. I was using the terminology that Mr. Yang 
used. If you weren't listening.
    Ms. Kamlager-Dove. I was listening but I was also getting 
your vibe.
    Ms. Hageman. OK. Mr. Roy. The gentlelady from Wyoming will 
proceed.
    Ms. Hageman. Almost all countries that conduct a consensus 
actually have a citizenship question, and the U.N. says that it 
is best practice to include a citizenship question in these 
censuses. Counties that ask about citizenship are Canada, 
Australia, Ireland, Germany, and Mexico. The source of this is 
The New York Times.
    Mr. Mayfield, I would like to focus on the Census Bureau's 
decision to utilize the differential privacy methodology for 
the first time in the 2020 Census.
    I am incredibly concerned that intentionally creating 
structural inaccuracy census data collection at the lowest unit 
has impacted the reliability of nationwide census counts, 
Congressional reapportionment, assignment of Presidential 
electors, redistricting, and Federal funding allocations.
    In light of these concerns, could you briefly explain the 
steps that the Census Bureau took when adopting and 
implementing this differential privacy within the 2020 Census?
    Mr. Mayfield. To put it in shorthand, Congresswoman, this 
was done at the civil servant level without any legal opinion 
being obtained. The decision was made by John Abowd, who is the 
Director of Privacy and Statistics, and a small group of people 
working with him. There was actually opposition from other 
parts of the bureau because the test repeatedly demonstrated 
that it would falsify data, including the block level that you 
mentioned, but anything below the State level.
    They proceeded with that because they wanted to do 
differential privacy, not because there was any need for 
differential privacy. Data swapping, which was the method used 
in the previous three censuses, had always been adequate, and 
to this day there is still no problem with it. There is a 2023 
study by researchers from Harvard, NYU, and Columbia that finds 
that data swapping is just as good as differential privacy, but 
it doesn't alter the data. There was no reason to do this.
    Now, to give you an example of just how bad it is, this is 
post-use of differential privacy--that study found the use of 
differential privacy, for instance, if you had three Hispanics 
on one block, you create a variance anywhere in the State of 
zero Hispanics or six Hispanics. In other words, 100 percent 
difference either way.
    All the data, as Mr. Miller alluded, below the State level 
has been subjected to differential privacy. Because of the way 
the algorithm works--it's a top-down algorithm--none of the 
data can be released in unaltered form. You cannot actually get 
the results of the survey below the State level. You may know 
there are nine million people in Indiana, but you don't know 
how many people there are in Muncie, you don't know how many 
people there are on Mayfield Street in Muncie.
    Ms. Hageman. They cooked the books, and they did so 
intentionally. Is that a good way of describing it?
    Mr. Mayfield. That is accurate.
    Ms. Hageman. All right. They didn't follow the 
Administrative Procedures Act, they didn't put this out for 
notice and comment, they didn't solicit information from 
people, statisticians, economists, States, or local governments 
about how best to do the census of counting their people to do 
as Mr. Yang says, which is to know how many people live in our 
country. They didn't do any of that?
    Mr. Mayfield. It's even worse than that, Congressman and 
Congresswoman. Excuse me. They didn't do notice and comment. 
There's a debate about whether or not that's required. There 
are numerous Committees to allude to something that 
Congresswoman Scanlon mentioned in her opening statement the 
Census interacts with consumers of census data and partners, 
including State and local governments, and including interest 
groups. Every single statistical group objected to this by 
letter. Every single State.
    The National Conference of Legislators objected. Maine 
objected. It's a Blue State. Utah objected, a Red State. The 
city of Alexandria, just across the water here, very Blue, 
objected. Maricopa County, very Red, objected. The House 
Progressive Caucus. They were right. They objected. The Mexican 
American Legal Fund. They objected. The Native American Tribes 
objected. Everyone knew--it was well-known that this would not 
work. The Census civil servants, a small group of them, went 
ahead with it because they wanted to do it, not because there 
was any need, and disregarding the fact that it made the census 
inaccurate the enumeration stage.
    Ms. Hageman. They did it because they wanted to cook the 
books and they wanted to manipulate the data to have the 
outcome that we actually had, which is overcounting people in 
six Blue States, or liberal States, and giving them additional 
Members in the House of Representatives. Is that fair?
    Mr. Mayfield. If I might respectfully disagree with that 
part, I believe it was done out of professional pride because 
there was an obsession with using differential privacy. Several 
other speakers have alluded to the use of internet data and 
supercomputers, which is what John Abowd mentioned.
    Congress does not exclude the use of outside data. If 
anyone here wants to grab census data and buy something from 
the internet, or buy a credit card company's data and combine 
them, that creates no violation. There is no problem with doing 
that. Section 9 of Title XIII bars only the disclosure of 
personal data; in other words, your census form that you filled 
out for your house.
    The errors that have been attributed with respect to the 
number of people are based on post-enumeration surveys. In 
other words, the Census does quality checks after the census. 
Those are models. They are not themselves enumerations. They 
are no good--are no better than the models and the data that's 
put in them. There are errors after every census that are 
believed.
    What you do is use that data to try to focus on your next 
census and all your other data collections to make sure that 
you don't miss other people, that you don't overcount them. It 
may be an educated guess that some States received more people 
and some States received fewer, but it is a guess. It is 
certainly no better than the modeling that the people in the 
bureau did.
    Ms. Hageman. OK. I know that I am out of time. What I hope 
comes out of this hearing, however, is that we have solutions 
of what Congress can do to make sure that these inaccuracies 
are addressed and that we never have this kind of mess again.
    I also would ask for unanimous consent to submit into the 
record, ``What You Need to Know About the Citizenship question 
in the census,'' July 2, 2019, by The New York Times.
    Mr. Roy. Without objection, that will be entered into the 
record. I thank the gentlelady from Wyoming. I now recognize 
the Ranking Member, Ms. Scanlon.
    Ms. Scanlon. Thank you, Mr. Chair. Thank you to all our 
witnesses because there is a lot to dig into here. It was a 
really interesting discussion.
    I guess there are a couple points of clarification. Mr. 
Yang, do you think there's general agreement that the purpose 
of the census clause is to get an accurate count of all 
persons?
    Mr. Yang. Certainly, that has been the history. It has been 
nonpartisan, that is the purpose of the census, as defined in 
the Constitution, and defined in the 14th Amendment for 
purposes of apportionment, is to count all persons. That is the 
literal text.
    Ms. Scanlon. We have considerable constitutional history 
and court opinion saying they did not choose to say 
inhabitants. They did not choose to say taxpayers. They did not 
choose to say citizens or voters. It is persons.
    Mr. Yang. That is correct. This came up in the context of a 
Supreme Court case called Evenwel where an argument was made 
that apportionment should be based solely on legal voters. The 
court, the Supreme Court in that case rejected that approach 
and said that we should be using total population. Total 
population or whole population for purposes of apportionment.
    Ms. Scanlon. Sure.
    Mr. Yang. That case was in 2016, so it was only 10 years 
ago, 5-9 years ago.
    Ms. Scanlon. Of course, there has been a lot of discussion 
about what questions should be on the census or not be on the 
census. I heard my colleague across the aisle talk about it 
being a good thing to put a citizenship question on the census, 
although context is important when we are talking about Canada, 
Ireland, or some of the other Nation States that were 
mentioned. They certainly do not have administrations that are 
actively engaged in hostility toward immigrants. That is an 
important distinction.
    When you were testifying you talked about the two biggest 
things that undermine accuracy in the census, and first, was 
privacy concerns and antigovernment sentiment. The second, was 
a lack of robust--get-out-the-census, get-out-the-count 
efforts. I certainly participated in count efforts in my home 
State.
    With respect to the privacy and antigovernment concerns, I 
wish Mr. Massie were here, because I know it is a big interest 
of his. In an era where we have got DOGE trolling through 
everyone's Social Security, and SNAP records, and voting 
records, and everything, can you talk a little bit about how 
those privacy concerns might be heightened right now?
    Mr. Yang. Well, this goes to--thank you for that question. 
This goes to the decrease in trust that Americans have in U.S. 
Government, which is unfortunate, but that is the case. That is 
because of--whether we want to talk about DOGE or what 
Representative Balint talked about, immigration enforcement. 
Certainly, that also breeds distrust within certain pockets of 
our community, whether it's the Hispanic community or the Asian 
community.
    When we are trying to determine an accurate census, all 
that context matters. Simply citing the history of how the 
census was used in the past when there might have been more 
trust in the government, is different than what we are looking 
at today.
    Ms. Scanlon. Yes, I certainly hear from my constituents 
that they are very, very concerned about these efforts to troll 
all the Federal data, and certainly the census would provide 
another opportunity to do that.
    We also have in your testimony on page 5, information about 
which groups were overcounted or undercounted in the 2020 
Census. I would note that non-Hispanic Whites were overcounted, 
but there were some pretty serious undercounts, as you've 
mentioned before, among Hispanic or Latino, Blacks, and 
children, et cetera. It does seem important that we try to have 
more robust counting in those areas.
    Mr. Yang. That's correct. To be clear, representative, 
overall the census was accurate. When compared to the 2010 and 
2000 Census, they were within--they were all considered 
statistically insignificant with respect to overcount or 
undercount. Certainly, when you compared the 1990, 1980 Census 
we did much better.
    That said, we recognize that there are overcounts and 
undercounts. We all agree we should continue to work on 
figuring that out and how best to do that. Certainly, for my 
community, the Asian community, part of this is outreach. Part 
of it is also language barriers that people face. Part of it is 
distrust of the government. Making sure we address all these 
barriers. For rural communities it's internet access, 
especially in this age where the census can be conducted by the 
internet. We should be thinking about those barriers to make 
sure how we get an accurate count.
    The last thing I might add quickly is also I would ask the 
Members of Congress to fully fund the Census Bureau. The budget 
right now--the request is around two billion, by our community 
1.8 billion. Right now, the funding is at 1.35 billion. If we 
want to address a lot of these technical issues as well as 
figuring out how to do it right to get an accurate count, 
robust funding is necessary.
    Ms. Scanlon. Yes, and the last question I had was with 
respect to some attempt to conflate the undercounting, which 
was admitted, of certain Republican-led States conflating that 
with some political animus as opposed to being undercounting 
relating to these already marginalized populations. Is there 
anything that you have seen to indicate that it was based on 
political motivation as opposed to those States just having 
marginalized populations which have been undercounted across 
the board?
    Mr. Yang. Yes, thank you for that question. We have the 
honor of working with the Census Bureau and they're dedicated 
civil servants. They're trying to get this right. They 
recognize that they did make mistakes and there were certain 
undercounts and overcounts. The reason is complex, like we've 
talked about. Part of it is distrust. Part of it is 
underinvestment by certain communities in making that count 
happen.
    When you look at it in the aggregate, especially when you 
look at where the overcounts and undercounts occurred, it's not 
fair to say that it only occurred in Red States or only 
occurred in Blue States. It occurred in a lot of different 
States, but it also was overall pretty accurate. We should 
think about all these in that context before making any snap 
judgments.
    Ms. Scanlon. I appreciate the Chair calling this so we can 
work on continual improvement of the process. Thank you.
    Mr. Roy. I thank the Ranking Member. I will now represent 
the gentleman from Wisconsin.
    Mr. Grothman. Thank you for being easygoing on the five-
minutes. That is what I do, too.
    OK. First, Mr. Yang, I just got to interject myself in here 
on something that you said that was I thought offensive. There 
is a three-fifths clause in our original Constitution. That was 
the result of a compromise. I suppose it could have been 100 
percent, but the reason it wasn't 100 percent is the freedom-
loving people did not want to give the slave States too much 
power in Congress. OK?
    You imply that the reason it wasn't 100 percent was because 
people were trying to say Black people were less than White 
people. That wasn't the point at all, you understand? The point 
is that the free States: Pennsylvania, New York, and New 
Jersey, those states did not want to give too much power to the 
slave States. It was not done to punish slaves. It was done to 
look down the road--eventually, we had a civil war anyway, but 
it was looking down the road to make sure that the slave States 
did not have too much power. OK? You understand that? I hope 
you understand that, but you just explain the three-fifth thing 
in a way to make America look worse in the eyes of young 
people. Do not appreciate that.
    Now a question for Mr. Miller. Has the census ever--
    Mr. Raskin. Mr. Chair, just a quick point of order. Would 
it be possible for me, after the gentleman speaks, to respond 
to that, because of the profundity and the depth of the 
statement he just made? I think it--
    Mr. Roy. It is the gentleman from Wisconsin's time.
    Mr. Raskin. I don't mean to--exactly. I don't want to 
detract from his time. I am wondering if maybe we could go for 
a second round just to explicate that.
    Mr. Roy. You and I can talk offline.
    Mr. Raskin. OK.
    Mr. Roy. We will let the gentleman from Wisconsin ask his 
questions.
    Mr. Raskin. OK. Very good. Thank you.
    Mr. Grothman. OK. Mr. Miller, has the census ever included 
a citizenship question?
    Mr. Miller. Yes, historically it has included the 
citizenship question.
    Mr. Grothman. OK. Why was it removed?
    Mr. Miller. That's speculative. That there were motives for 
that. States would be motivated by it if they get more money 
from the Federal Government. There're partisan reasons why you 
would want to do it. There's a lot of reasons and it's probably 
fairly complicated.
    Mr. Grothman. Who was the President at the time it was 
removed, do you know?
    Mr. Miller. The last one was at '50s, is what we said--
1950s.
    Mr. Groth. Truman? OK. Assuming you are right. Has the 
Supreme Court ever held that it is illegal to include this 
question?
    Mr. Miller. No, I don't believe the Supreme Court has ever 
weighed in to say that you cannot ask a citizenship question.
    Mr. Grothman. Could President Trump and Congress Secretary 
Lutnick add a citizenship question to the 2030 Census?
    Mr. Miller. Yes.
    Mr. Grothman. OK. Could you give me some benefits, I am 
shocked that it's not there already, but do you want to 
speculate on some benefits we would get if we added such a 
question?
    Mr. Miller. Well, it would impact especially if you got rid 
of differential privacy, you could know how to allocate Federal 
funding formulas more accurately to make sure that it's going 
to citizen or lawful permanent resident populations that 
legally qualify for them. If you want to have this impact 
redistricting and you want to argue on a constitutional basis 
that political districts should only represent citizens, or 
citizens and lawful permanent residents, that you would need to 
know that data. That would have a massive impact on how 
political maps are made and who is in Congress.
    Mr. Grothman. Couldn't we also assume that people who are 
not here legally probably aren't going to be hanging around 
that much longer?
    Mr. Miller. I don't know. A lot of them have been here for 
a long time. Some of them are seasonal workers and leave after 
a couple of years. It's hard for me to answer that precisely 
with such a large population.
    Mr. Grothman. OK. Not across the board, but wouldn't one 
expect that if some people were here illegally or on a 
temporary visa that they weren't going to be here for the whole 
10 years, or maybe even--
    Mr. Miller. That's correct. There's a lot of movement of 
that population both into and out of the United States of 
America.
    Mr. Grothman. OK. Could you explain the differential 
privacy controversy, I will put it?
    Mr. Miller. Yes. Basically, you have data, and there's been 
previous methods of keeping basically recognizing data privacy 
laws. There were different methods of protecting privacy. This 
is a new method, but it's highly flawed because it scrambles 
all the data. It literally deconstructs an entire person, 
reconstructs them in the aggregate all over the place.
    There are arguments that it will disproportionately help 
urban areas. There are arguments it will disproportionately 
hurt rural areas. There are racial issues here. Basically, it's 
fake data below the State level and it's really hard to create 
political districts that are accurate and representative of the 
voting population especially when you don't have accurate 
numerical population data at a granular and semigranular level.
    Mr. Grothman. Would you support returning to what we will 
call swapping for the 2030 Census?
    Mr. Miller. I think there's several other proposals--that 
is combined with the ability to turn off characteristic data 
until you're at statistically significant levels. There are 
other methods that strategies are multitiered that are 
mentioned by entities like IMPS that would work. Essentially 
yes.
    Mr. Grothman. OK. Thank you.
    Mr. Raskin. Would the gentleman yield? FBI--
    Mr. Roy. I think the gentleman from Wisconsin would--
regarding?
    Mr. Raskin. I was just wondering if you--I just wanted the 
opportunity to respond to Mr. Grothman's intervention.
    Mr. Roy. It is the gentleman's time, but out of courtesy to 
the Ranking Member, I'll give the gentleman 30 seconds.
    Mr. Raskin. OK. I just want to say that the analysis he 
advanced is historically obtuse and morally disoriented. The 
slave States took the position that the enslaved African 
Americans should count 100 percent for the purposes of 
reapportionment, but for those purposes only. They didn't have 
any civil rights. They didn't have any voting rights. They 
couldn't run for office. They had no civil liberties. They were 
property. The Northern States said they should not count at 
all.
    Mr. Roy. Reclaiming our time.
    Mr. Raskin. They should count zero. They arrived at the 
three-fifths--
    Mr. Roy. Reclaiming the time. We are not going to have a 
history lesson here. The gentleman from Wisconsin was making a 
point with respect to the often-used three-fifths reference. 
With respect--
    Mr. Raskin. I was trying to explain what the historical 
genesis of it is.
    Mr. Roy. The history of it, the gentleman from Wisconsin 
characterized it from his perspective. It was important for him 
to put that on the record. It has been asked and answered and 
we don't need to have a history lesson it. I am going to go 
ahead and proceed with my questions.
    Mr. Roy. This hearing has been illuminating on a number of 
different levels. I would like to ask just a simple question 
for the panel generally, which is very specifically was the 
2020 Census accurate? Mr. Mayfield?
    Mr. Mayfield. At the State and national level it was within 
a margin of error for modern censuses. The State level it was 
not.
    Mr. Roy. Mr. Rodriguez?
    Mr. Rodriguez. Considering that it counted illegal and 
nonimmigrant aliens, it was inaccurate according to the 
dictates of the Constitution.
    Mr. Roy. Mr. Miller?
    Mr. Miller. It was the most inaccurate census in modern 
times in my opinion.
    Mr. Roy. Mr. Yang?
    Mr. Yang. At the State and national levels it was accurate. 
At the sublevels below that it was inconsistent at times, but 
overall, still did very well.
    Mr. Roy. Was it true that in 2022 that the Census Bureau 
itself acknowledged that there were significant errors and 
significant discrepancies? Is that correct, Mr. Mayfield?
    Mr. Mayfield. That is correct.
    Mr. Roy. All right. Did it have a significant impact on 
States in that there was undercounting and overcounting of at 
least 14 States? Mr. Mayfield?
    Mr. Mayfield. That is the Census' position as of 2022.
    Mr. Roy. Now, was it also accurate that, in fact, the 
undercounting was often directed toward more conservative 
States with more Republican representation and the overcounting 
was directed toward what we might call Blue States with more 
Democrat representation?
    Mr. Mayfield. I can't address your use of the word 
direction. That is certainly what the modeling suggests was the 
result.
    Mr. Roy. Mr. Miller, would you add to that?
    Mr. Miller. Yes, the Census Bureau would acknowledge that 
this would have been the outcome.
    Mr. Roy. To the tune of as many as 500,000 in the State of 
Texas, for example?
    Mr. Miller. That's correct, costing Texas an additional 
Congressional seat.
    Mr. Roy. Let's get to the heart then of why. Why is that 
the case? We have posited here in this hearing--I have heard a 
number of folks represent that one of the reasons is because of 
illegal immigrants. True or false, is the issue of how we count 
involving illegal immigrants having a direct impact on 
representation in Congress? Mr. Mayfield?
    Mr. Mayfield. That is undeniably true.
    Mr. Roy. Mr. Rodriguez?
    Mr. Rodriguez. I agree. It's been true for at least the 
last three censuses.
    Mr. Roy. Mr. Miller?
    Mr. Miller. It's a mathematical certainty.
    Mr. Roy. Mr. Yang?
    Mr. Yang. Undocumented immigrants are required to be 
counted under the Constitution.
    Mr. Roy. Do they have a direct impact on how we apportion 
and how districts are getting set up?
    Mr. Yang. That is less clear to me.
    Mr. Roy. Let me ask you a question, Mr. Yang. You posited 
earlier some theories about how we count people and that we 
should count everybody for apportionment purposes. If 75 
million people were to come into the State of California 
between now and 2030, should we have 100 new Congressional 
seats in California, if all 75 million of those people were 
illegally present in the State of California?
    Mr. Yang. That's the way the Constitution is currently 
constructed as I understand it.
    Mr. Roy. That is taking issue with that, by the way, that 
the Constitution requires that we apportion based on people who 
are here illegally, which a number of the other people on the 
panel have questioned, and at no point has the Supreme Court 
said that is the case, then we are saying here--the Democrat 
witness is saying that if we had 75 million people illegally 
flood into the State of California, we must have 100 
representatives--again, rounding the math there--added to the 
State of California? That is extraordinary to me.
    I do want to followup and finish on this question of the 
differential privacy. The other question that has been raised 
here, which is highly problematic on a less-partisan basis, is 
the extent to which we have the Census Bureau adopting, by Mr. 
Mayfield's testimony, by edict of a civil servant bureaucrat at 
the Census Bureau, an approach to estimating and guessing the 
population based on something that was attacked by numerous 
groups, questioned by numerous groups, and is now proven to be 
statistically problematic, that it is actually causing massive 
problems with respect to our counting. Is that fair, Mr. 
Mayfield?
    Mr. Mayfield. That is accurate.
    Mr. Roy. Mr. Rodriguez, is that fair?
    Mr. Rodriguez. It's fair.
    Mr. Roy. Mr. Miller?
    Mr. Miller. We may disagree on a lot of different things, 
but there's a bipartisan consensus that this is a problem, a 
big problem.
    Mr. Roy. Mr. Yang, you said something that needed fine 
tuning, but you also seem to acknowledge that there are 
significant problems with respect to the way this is being 
handled now.
    Mr. Yang. As a new policy I agree that this is something 
that needs to be evaluated, absolutely.
    Mr. Roy. Mr. Miller, you have thrown out a couple ideas. I 
want to conclude on that point because I think it is really 
important that there are other ways to go about doing this. 
Swapping, you get into that. The issue here for everybody to 
understand is you have laws that say you got to protect 
privacy. You have got a massive file that is protected at 
unbelievable levels of security and inability to look at the 
data. Therefore, we have to figure out how to know that we have 
an accurate census. This differential privacy is raising 
massive concerns on a nonpartisan basis, right? A Harvard 
study: Independent groups, groups on the Left, and groups on 
the Right. It would seem to me that we should come to a 
consensus on how we should approach this.
    Could the gentleman finish filling in that question and 
that point?
    Mr. Miller. Absolutely. At the end of the day there is a 
constitutional purpose for all this. A privacy statute cannot 
be a reason by which to ignore the constitutional outgrowths 
and outflows of what the purpose of this data is.
    If we have a privacy standard that is causing--I think most 
people would agree with this at this point, it's significant 
data distortion that is impacting all sorts of Federal funding 
formulas, all sorts of potentially definitely redistricting, 
potentially depending on how it's not everything that we 
believe it is, and not everything that they're purporting to 
say it is, in theory it's not supposed to affect apportionment, 
I don't have access to the data. I can't verify that. That's 
how it's supposed to work.
    At the end of the day, we should defer to a privacy method 
that is also as good and does not create as many constitutional 
issues as we have seen. If that is achieved by swapping and 
turning off data, we need to get our smart people together and 
figure out another option.
    Mr. Roy. You were suggesting--in closing, my time is over--
the--turning off the data. That was an approach you are 
suggesting to try to have an approach.
    Mr. Yang, can I just ask you on a nonpartisan basis with 
just a little indulgence, do you have a perspective on that? 
Because I saw you nodding--maybe all of a sudden that 
intellectual chewing on it as to whether that would be an 
approach that might help solve the problem of managing privacy 
but not having data that is problematic.
    Mr. Yang. Like I said, this is worth evaluating. This is a 
part of what happens after ever census is the Census Bureau 
looks at what worked, what didn't. It acknowledges what 
mistakes are made. It acknowledges in this case that there were 
certain overcounts and undercounts. That's no different than 
any other census. Now, the job of the Census Bureau is--with 
guidance from all of you, is to move forward and make that 
system even better for the next census.
    Mr. Roy. All right. I thank the panel. I now know that my 
colleague from Texas--
    Ms. Scanlon. I would just seek unanimous consent.
    Mr. Roy. Sure.
    Ms. Scanlon. We have discussed the census after review 
quite a bit, so I would like to seek unanimous consent to 
introduce the GAO report on the 2020 Census: ``Coverage, 
Errors, and Challenges to Inform the 2030 Plans.'' There have 
been a lot of misstatements about what it shows, so it is good 
for everybody to have access to it.
    Mr. Roy. Without objection, we will insert that into the 
record.
    Ms. Scanlon. Thank you.
    Mr. Roy. I will now recognize the gentleman from Texas, Mr. 
Hunt.
    Mr. Hunt. Thank you, Mr. Chair. The time has come to 
elucidate the American people in the census manipulation that 
Democrats have been using to influence American elections for 
years.
    In 2018, Republican leadership, including the President 
himself, called for a citizenship question to be included in 
the 2020 Census Reports. To no one's surprise, when the 
Democrats took control, these requests went unanswered and the 
question of citizenship was waived. The fact remains that the 
concept of sanctuary cities and radical Blue States ignoring 
immigration law and using the illegal population to manipulate 
the lines of Congressional districts is in fact 
unconstitutional.
    Not only are there severe constitutional concerns from the 
inclusion of illegal immigrations, but the Census Bureau 
admitted to having made several, quote, ``errors'' in their 
2020 Census Report. Convenient, seeing that as in 2020 Donald 
Trump was on top of the ticket.
    In 2020, the bureau undercounted in primarily deep Red 
States such as Arkansas, Florida, Mississippi, Tennessee, and 
Texas, all Red, while overcounting in radical Left Blue States 
like Delaware, Hawaii, Massachusetts, Minnesota, New York, 
Ohio, and Rhode Island. This egregious error led to many States 
being denied proper representation in Congress and the 
Electoral College. So much so that these errors cost 
Republicans not one, not two, not three, not four, not five, 
but six seats in the House.
    In addition to the 2020 miscounting, including illegal 
immigrants in the census has improperly granted radical Left 
Blue States 12, 12 additional seats in the U.S. House of 
Representatives. That is a total of 18 seats gained. That is a 
huge problem. Those are the facts.
    Mr. Mayfield, thank you so much for being here. Sir, I have 
a question for you if you don't mind. You, sir, are a seasoned 
litigator who has practiced in matters ranging from complex 
commercial litigation to constitutional and administrative law. 
In your expert opinion,--I want you to really speak about this 
in long form because I want this recorded--should illegal 
aliens be included in the apportionment process under the 14th 
Amendment?
    Mr. Mayfield. The Supreme Court has never directly 
addressed that, Congressman. For apportionment purposes as 
Congress has interpreted it the Supreme Court has held that it 
currently applies to all people regardless of citizenship. 
There is certainly an open question as to whether or not--if 
Congress were to direct the Census Bureau to do it differently 
as to whether or not that would be legal.
    Mr. Hunt. OK. In regards to thinking more of a high-level, 
in terms of being a citizen and what it means to be a citizen 
in this country--and I do believe that being a citizen in this 
country means that you have the right to choose the leadership, 
if you are a tax-paying legal citizen in this country. If you 
are an illegal person in this country, should you under any 
circumstances be allowed to vote and choose leadership in this 
country?
    Mr. Mayfield. That wouldn't be an expert opinion that--as a 
citizen I would object to that.
    Mr. Hunt. What about you, Mr. Rodriguez?
    Mr. Rodriguez. I also object to that.
    Mr. Hunt. Mr. Miller?
    Mr. Miller. Correct. Citizens should not be--or illegal 
aliens should not be voting.
    Mr. Hunt. That applies to you also, Mr. Yang. I would love 
to hear your response to this question.
    Mr. Yang. Noncitizens are not allowed to participate in 
Federal elections.
    Mr. Hunt. OK. Are they participating in Federal elections?
    Mr. Yang. The studies have shown that there are very few 
instances in which they have.
    Mr. Hunt. That number needs to be zero. As somebody who is 
a proud Texan, we, and in Florida, have done our best to get 
that number to zero. In spite of the fact that I just voted a 
couple of weeks ago, and we voted with paper ballots, that we 
had to show an ID for, they then verified my address and where 
I lived. Then, I had to put said piece of paper through a 
machine, copied it. They gave me another copy. They gave me my 
very proud ``I Voted'' sticker. Even with those stringent 
rules, with my daughter who is seven years old, was actually 
with me. She too got an ``I Voted'' sticker. Guess what, with 
those stringent laws we still have illegals voting in Federal 
elections.
    The question is not even about what is happening in Texas. 
If it is happening in Texas, you have to imagine that it--while 
it may seem like a minuscule amount to you, sir, that number 
needs to be zero. If it is happening in Texas with those 
stringent rules, imagine what is happening in other Blue States 
that don't have anything that closely resembles that level of 
redundancy to ensure that the person that voted in that 
election is in fact a citizen that has an address and has an 
ID.
    With that, I yield back the remainder of my time. Thank you 
very much.
    Mr. Roy. I thank the gentleman from Texas.
    That concludes today's hearing. We thank the witnesses for 
appearing before the Subcommittee today. Without objection, all 
Members will have five legislative days to submit additional 
written questions for the witnesses or additional materials for
