Constitutionality of Excluding Aliens from the Census: Apportionment and Redistricting

Summary
In the 2010 decennial census, the Census Bureau will attempt to count the total population of the
United States. This includes, as in previous censuses, all U.S. citizens, lawfully present aliens,
and unauthorized aliens. Some have suggested excluding aliens, particularly those who are in the
country unlawfully, from the census count, in part so that they would not be included in the data
used to apportion House seats among the states and determine voting districts within them.
One question raised by this idea is whether the exclusion of aliens could be done by amending the
federal census statutes, or whether such action would require an amendment to the Constitution.
The Constitution requires a decennial census to determine the “actual enumeration” of the “whole
number of persons” in the United States. The data must be used to apportion the House seats
among the states, although there is no constitutional requirement it be used to determine intrastate
districts. It appears the term “whole number of persons” is broad enough to include all
individuals, regardless of citizenship status, and thus would appear to require the entire
population be included in the apportionment calculation. As such, it appears a constitutional
amendment would be necessary to exclude any individuals from the census count for the purpose
of apportioning House seats.
From time to time, Congress has considered legislation that would exclude all aliens or only
unauthorized aliens from being included in the census to apportion House seats among the states.
Such legislation would have either amended the Census Clause of the Constitution or enacted or
amended federal census statutes. In the 111th Congress, legislation has been introduced that uses
both approaches. The Fairness in Representation Act would statutorily exclude aliens from the
population count for apportionment purposes (H.R. 3797 and S. 1688). Under the above analysis,
it would not appear to be constitutionally sufficient for Congress to amend the federal census
statutes in such manner. Meanwhile, H.J.Res. 111 would take the other approach and amend the
Constitution so that only U.S. citizens would be counted in the apportionment calculation.
Other legislation in the 111th Congress would not raise the same constitutional issues since they
would not appear to require the exclusion of any individuals for apportionment purposes. An
amendment introduced by Senator Vitter to the Commerce, Justice, Science, and Related
Agencies Appropriations Act, 2010 (S.Amdt. 2635 to H.R. 2847), would have cut off funding for
the census unless the census form included questions regarding citizenship and immigration
status. The amendment was subsequently ruled to be non-germane. On the other side of the issue,
the Every Person Counts Act (H.R. 3855) would prohibit the Census Bureau from asking about
U.S. citizenship or immigration status.

Constitutionality of Excluding Aliens from the Census: Apportionment and Redistricting

Introduction
In the 2010 census, as in prior decennial censuses, the total population of the United States will
be counted, including U.S. citizens, lawfully present aliens, and unauthorized aliens.1 Some have
asked whether aliens, particularly those in the country unlawfully, should be excluded from the
census count.2 It appears one concern is that these individuals are included in the data used to
apportion House seats among the states and determine voting districts within them, which some
perceive as unfair to states or districts with small alien populations.3 One question raised by this
idea is whether the exclusion of aliens could be done by amending the federal census statutes
(Title 13 of the U.S. Code), or whether such action would require an amendment to the
Constitution.
The Constitution requires a decennial census to determine the “actual Enumeration” of the
“whole number of persons” in the United States. 4 The data must be used to apportion the number
of House seats among the states.5 While not required by the Constitution, the data are used for
other purposes as well, including by the states to determine voting districts within a state.
The Constitution expressly vests Congress with the authority to conduct the census “in such
Manner as they shall by Law direct.”6 Congress has delegated this responsibility to the Secretary
of Commerce and, within the Department of Commerce, to the Bureau of the Census.7 The
Census Bureau counts the total resident population of the states, with each individual counted at
his or her “usual residence.”8 This includes both citizens and aliens.9
There is no legal requirement that the Census Bureau collect information regarding citizenship
status. The 2010 census form sent to all households will not include questions regarding
citizenship status or place of birth.10 The Commerce Secretary has used his discretion11 to ask for

1 The three main components of the unauthorized resident alien population are (1) aliens who overstay their
nonimmigrant visas, (2) aliens who enter the country surreptitiously without inspection, and (3) aliens who are admitted
on the basis of fraudulent documents.

three fifths of all other Persons. The actual Enumeration shall be made within three Years after the first Meeting of the
Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law
direct …”); Amend. XIV, § 2, cl. 1 (“Representatives shall be apportioned among the several States according to their
respective numbers, counting the whole number of persons in each State, excluding Indians not taxed.”).

Sixteenth Amendment removes “taxes on income” from the requirement of apportionment. U.S. CONST. Art. 1, § 2, cl.

such information on the American Community Survey (ACS), which is sent monthly to a
sampling of households.12 Historically, questions regarding citizenship status have not been
consistently included in the census population surveys.13 At least two early censuses (1820 and
1830) included a category for foreigners not naturalized,14 and later censuses asked about place of
birth.15 In modern times, the census questionnaire sent to all households has not included such
questions, although the questionnaire sent to a sampling of households (the “long form,” which
has been replaced by the ACS) has asked for such information.
Legislation in the 111th Congress
From time to time, Congress has considered legislation that would exclude all aliens or only
unauthorized aliens from being included in the census to apportion House seats among the states.
A discussion of selected legislation from prior Congresses is included in the Appendix. In the
111th Congress, several bills have been introduced that would amend the federal census statutes to
explicitly address the treatment of unauthorized aliens. The Fairness in Representation Act (H.R.
3797 and S. 1688) would require the Commerce Secretary to include some means (e.g., a
checkbox) for respondents to indicate they are U.S. citizens or lawfully present in the country on
the census forms sent to all households. Additionally, the Commerce Secretary would be required
to make adjustments to the data to prevent unauthorized aliens from being counted for
apportioning House seats among the states.
An amendment introduced by Senator Vitter to the Commerce, Justice, Science, and Related
Agencies Appropriations Act, 2010 (S.Amdt. 2635 to H.R. 2847) would have cut off funding for
the census unless the census form included questions on U.S. citizenship and immigration
status.16 The amendment did not require the information be used for any purpose (i.e., to

Secretary shall … take a decennial census of population … in such form and content as he may determine…. In
connection with any such census, the Secretary is authorized to obtain such other census information as necessary.”);
13 U.S.C. § 193 (“In advance of, in conjunction with, or after the taking of each census provided for by this chapter, the
Secretary may make surveys and collect such preliminary and supplementary statistics related to the main topic of the
census as are necessary to the initiation, taking, or completion thereof.”).

13 The earliest laws relating to immigration were laws providing for naturalization of foreign-born persons, prohibitions
on the entry of certain types of aliens, such as criminals, and restrictions on the entry of foreign workers (specifically,
the Chinese). The current framework for immigration was not established until the mid-twentieth century, so there
would have been minimal basis for detailed information on immigration status. Currently, certain statistics concerning
immigrant status may be collected and maintained by other federal agencies. The Department of Homeland Security
maintains statistics regarding visa issuance. Nonimmigrant visa holders are permitted to enter and stay in the United
States for limited periods; persons who enter as immigrants or who adjust their nonimmigrant status to lawful
permanent resident status are permitted to remain in the United States indefinitely. Both the DHS and Executive Office
of Immigration Review in the Department of Justice maintain statistics regarding grants of asylum. (Asylees may apply
for lawful permanent resident status.) Statistics regarding unauthorized aliens have been published by various
government agencies and non-governmental organizations, but are subject to debate and dispute. For more information,

disregard certain individuals from the apportionment calculation). The amendment was
subsequently ruled to be non-germane.
H.J.Res. 111 would amend the Constitution so that only U.S. citizens would be counted in the
apportionment calculation. Specifically, it would amend the Constitution to read “Representatives
shall be apportioned among the several States according to their respective numbers, which shall
be determined by counting the number of persons in each State who are citizens of the United
States.”
On the other side of the issue, the Every Person Counts Act (H.R. 3855) would prohibit the
Census Bureau from asking about U.S. citizenship or immigration status.
Constitutional Analysis
While the Constitution permits Congress to conduct the census “in such Manner as they shall by
Law direct,”17 the census cannot be done in a way that is constitutionally impermissible. Thus,
one question raised by the above legislation is whether they are consistent with the constitutional
requirements for the decennial census.
It seems clear that Congress could, under its broad constitutional authority to conduct the census,
statutorily require the Commerce Secretary to collect information regarding citizenship status.18
The constitutionality of the other provisions in the legislation would appear to depend on whether
all aliens are required to be included in the census count for any reason. If so, then it would
appear that any exclusion would have to be done by constitutional amendment. On the other
hand, if the Constitution requires such individuals to be excluded from the census count, then
Congress could not prohibit the Commerce Secretary from asking questions about citizenship and
immigration status.
As mentioned above, it appears some are concerned that aliens, particularly those individuals in
the country unlawfully, are included in the data used to apportion House seats among the states
and determine voting districts within the states. The next section analyzes whether Congress
could statutorily exclude aliens from the census count for these purposes or whether any such
exclusion would have to be done by constitutional amendment.
Data for Apportionment Purposes
Constitutional issues could arise if aliens were excluded by statute from the census count for
purposes of apportioning House seats among the states. This is because it appears the term
“persons” in the original Apportionment Clause and Fourteenth Amendment was intended to have
a broad interpretation that is likely expansive enough to include unauthorized aliens. If true, any

proposal to generally exclude unauthorized aliens would have to be in the form of a constitutional
amendment.19
The term “persons/people” appears throughout the Constitution,20 with its meaning evaluated in
the context of each provision. On its face, the term’s plain language meaning refers to individuals.
However, it has been held to have a less obvious meaning in certain contexts; i.e., to include
corporations for the Fourteenth Amendment’s due process and equal protection guarantees.21
Here, the question is whether the term refers to only a subset of individuals, U.S. citizens, for
purposes of apportioning House seats among the states.
It seems that “persons” is not limited to “citizens” as the Framers would have likely used that
term instead had it been their intent. The Constitution uses both the terms “persons/people” and
“citizens of the United States,” and the terms do not seem intended to be interpreted identically;
rather, “citizens of the United States” appears to be a subset of “persons/people.”22 Courts have
generally held that aliens, including unauthorized aliens, are “persons” in the context of other
constitutional provisions, including other parts of the Fourteenth Amendment.23 While it does not
appear that any court has decided the meaning of the term “persons” for apportionment
purposes,24 a federal district court did state in dicta that the term clearly includes unauthorized
aliens.25
It could be argued that certain aliens should not be included in the category of “persons” for
purposes of apportionment because of their legal or voting status. On the other hand, historically,
those without the right to vote or with inferior legal status, including women, children,26 and

19 Some commentators have argued there is no constitutional requirement that one class of aliens—illegal aliens—be
counted for purposes of apportionment. See, e.g., Charles Wood, Losing Control of America’s Future: The Census,
Birthright Citizenship, and Illegal Aliens
, 22 HARV. J.L. & PUB. POL’Y 465 (1999)(arguing the Constitution permits a
stricter test for residence than the Census Bureau’s “usual residence” standard and does not require the counting of
illegal aliens because they would not have the requisite stable inhabitancy in a state); but see Note: A Territorial
Approach to Representation for Illegal Aliens
, 80 MICH. L. REV. 1342 (1981-82)(arguing the Constitution, as evidenced
by its language and history, requires illegal aliens be included).
20 See, e.g., U.S. CONST. Amend. I (“Congress shall make no law ... abridging ... the right of the people peaceably to
assemble, and to petition the Government for a redress of grievances”); Amend. II (“A well regulated Militia, being
necessary to the security of a free state, the right of the people to keep and bear Arms, shall not be infringed”); Amend.
V (“No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment
of a Grand Jury …”).
21 See Grosjean v. American Press Co., 297 U.S. 233, 244 (1936).
22 See, e.g., U.S. CONST. Art. I, § 2, cl. 2. (“No Person shall be a Representative who shall not have attained to the age
of twenty five Years, and been seven Years a Citizen of the United States, and who shall not, when elected, be an
Inhabitant of that State in which he shall be chosen.”).
23 See, e.g., Plyler v. Doe, 457 U.S. 202, 210 (1982) (“Whatever his status under the immigration laws, an alien is
surely a ‘person’ in any ordinary sense of that term. Aliens, even aliens whose presence in this country is unlawful,
have long been recognized as ‘persons’ guaranteed due process of law by the Fifth and Fourteenth Amendments.”).
This does not mean that aliens must be afforded the same benefits as citizens. See Matthew v. Diaz, 426 U.S. 67, 78-79
(1976).
24 While several cases have been brought challenging the inclusion of unauthorized aliens, courts have found the
plaintiffs lacked standing to bring suit. See Ridge v. Verity, 715 F. Supp. 1308 (W.D. Penn. 1989); Federation for
American Immigration Reform (FAIR) v. Klutznick
, 486 F. Supp. 564 (D.D.C. 1980) (three-judge panel).
25 See FAIR, 486 F. Supp. at 576 (“The language of the Constitution is not ambiguous. It requires the counting of the
‘whole number of persons’ for apportionment purposes, and while illegal aliens were not a component of the
population at the time the Constitution was adopted, they are clearly ‘persons.’”).
26 It could be argued that the treatment of women and children should not be compared to that of unauthorized aliens
who are violating the laws of the United States. On the other hand, if the purpose of the census is understood to be

convicts, have been included. It should also be noted that some states have historically permitted
aliens to vote under certain circumstances.27 Furthermore, the fact that slaves were to be partially
counted when they enjoyed few rights seems to suggest the Apportionment Clause language was
intended to be broadly inclusive.28 Similarly, the fact that the Framers felt compelled to specify
the exclusion of “Indians not taxed” may suggest “persons” was understood to otherwise include
individuals residing within a state, regardless of legal status.29 Thus, it can be argued that “[b]y
making express provisions for Indians and slaves, the Framers demonstrated their awareness that
without such provisions, the language chosen would be all-inclusive.”30
The debates surrounding the original Apportionment Clause and the Fourteenth Amendment
appear to add further support for the conclusion that the term “persons” was intended to be
broadly interpreted. The Framers adopted without comment or debate the term “persons” in place
of the phrase “free citizens and inhabitants” as the basis for the apportionment of the House,31
thus suggesting the term “persons” includes free citizens and any other individuals who would be
considered “inhabitants.” According to James Madison, apportionment was to be “founded on the
aggregate number of [the states’] inhabitants.”32 During the debate on the Fourteenth
Amendment, Congress specifically considered whether the count was to be limited to persons,
citizens, or voters.33 The term “persons” was used instead of “citizens” due, in part, to concern
that states with large alien populations would oppose the amendment since it would decrease their
representation.34 Another concern with using the term “citizen” was that it “would narrow the
basis of taxation and cause considerable inequalities in this respect….”35 Congress may also have
been influenced by the fact that aliens could vote in some states.36 Congress has subsequently
considered excluding aliens from the apportionment calculation on several occasions,37 and at
least some Members have indicated that any such exclusion would have to be done through

counting all individuals who are actually inhabitants of the United States, then the comparison would be appropriate.
27 Article I, § 2, cl. 1 provides that the voter qualifications in each state for those electing Representatives shall be the
qualifications required by state laws for voters electing the most numerous branch of the State legislatures. Historically,
some states extended the franchise for electing the most numerous branch of the state legislatures to lawful aliens for
all elections. See The Constitution of the United States of America: Analysis and Interpretation, S. Doc. No. 108-17
283, fn. 1220 and accompanying text (2002); Jamin B. Raskin, Legal Aliens, Local Citizens: the Historical,
Constitutional and Theoretical Meanings of Alien Suffrage
, 141 U. PA. L. REV. 1391 (1993). Although today no state
extends the franchise to aliens generally, some states do permit lawful permanent residents to vote in certain local
elections, such as school board elections. The rationale appears to be that lawful residents have all the obligations of
local residents, such as local property tax payments, and may have children attending local schools who are either
lawful permanent residents or U.S. citizens themselves; therefore, they should be permitted to vote in certain local
elections.

constitutional amendment since the Constitution otherwise requires total population as the basis
for apportionment.38
Furthermore, while the Constitution expressly grants Congress the authority to grant citizenship,39
it can be argued there is no indication that Congress was given similar power to grant the status of
being a “person.”40 Thus, under this argument, Congress would not have the authority to
statutorily exclude certain groups of individuals from the definition of “persons” and any such
change would have to be done by amending the Constitution. On the other hand, it could be
argued that Congress’s broad constitutional authority over the census, apportionment, and
immigration permits it to exclude certain aliens, particularly undocumented aliens.41
The argument could be made that counting aliens as “persons” for apportionment purposes dilutes
the voting power of citizens in states without significant numbers of aliens and, therefore, is
inconsistent with the Supreme Court’s decision in Wesberry v. Sanders42 that requires
congressional districts be drawn equal in population to the extent practicable (i.e., “one person,
one vote”).43 However, Wesberry and its progeny involve intrastate, as opposed to interstate,
disparities,44 and the Court has indicated in another line of cases that the Wesberry standard does
not apply to interstate apportionment.45 Because each state must have at least one House district
and a fixed number of Representatives must be allocated among all states, votes in states with
populations less than the ideal district are “more valuable than the national average” and it is
“virtually impossible to have the same size district in any pair of States, let alone in all 50.”46
Therefore, while the goal of “complete equality for each voter” under the Wesberry standard is
“realistic and appropriate for state districting decisions,” the Court has explained that it is
“illusory for the Nation as a whole.”47 While this second line of cases does not address the
specific issue of whether aliens must be counted for apportionment purposes, the cases do seem to
undermine the argument that Wesberry and its progeny require their exclusion.48
Some have pointed to the fact that the census has historically included questions about
citizenship, thus perhaps suggesting that a distinction has been made between citizens and aliens
for purposes of counting individuals. It is true that at least two early censuses (1820 and 1830)

38 See, e.g., 86 Cong. Rec. 4371-72 (1940)(remarks by Rep. Celler asserting that the term “persons” refers to all
individuals, including aliens who are in the country unlawfully); 1980 Census: Counting Illegal Aliens, Hearings on S.
2366 Before the Subcomm. on Governmental Affairs
, 96th Cong. 12 (1980) (statement by Sen. Javits asserting that the
Constitution requires counting all aliens for apportionment purposes).

43 See Murphy, supra note 41.
44 This distinction is important because the Constitution only requires the use of census data for apportionment among
the states, not for redistricting and reapportionment within them. Thus, states can determine what data shall be used for
redistricting within a state. This issue is discussed further in the next section.

included a category for foreigners not naturalized49 and later censuses asked about place of
birth.50 However, such information was not used to exclude any aliens from the census count.
Rather, it is clear that such individuals were included in the total count,51 and it appears the data
was collected for informational purposes (similar to how information was collected about age,
occupation, etc). It does not appear that aliens have been excluded from any census.
Data Used for Intrastate Redistricting
The U.S. Constitution does not require the use of federal decennial census data for intrastate
congressional and state legislative redistricting. It only provides for the use of census data for
apportionment among the states, not for redistricting and reapportionment within them. Federal
courts have held that states are not required to use federal census data for redistricting, and
therefore states can determine what data will be used for redistricting within a state.52
Federal courts have considered cases where state legislatures did not use federal decennial census
data or even total population data as the basis for redistricting activities. Depending on the factual
circumstances, the courts have upheld or invalidated the use of alternatives to official federal
decennial data or total population data. For example, in the 1969 decision Kirkpatrick v. Preisler53
involving Missouri’s congressional redistricting plan, the Supreme Court, while invalidating the
plan, nevertheless indicated that the use of projected population figures was not per se
unconstitutional and that states may properly consider such statistical data if such data would
have a high degree of accuracy (however, the Court also stated that the federal decennial census
data were the best data available). In Kirkpatrick, the state legislature apparently performed rather
haphazard adjustments and projections based on total population and the Court found that the
legislature had not justified its methodology. In Burns v. Richardson,54 the Supreme Court held
that, in state legislative redistricting cases, the Constitution “does not require the states to use
total population figures derived from the federal census as the standard” of measurement. The
Court noted that in earlier cases it was careful to leave open the question of what population basis
was appropriate in redistricting activities, even though in several cases total population figures
were in fact the basis for comparison when determining whether the Equal Protection Clause of
the Constitution had been violated. The Court recognized that, in a particular case, total

population might not be the appropriate basis for redistricting plans. In the Burns case, Hawaii
had used the number of registered voters as the basis for redistricting the state senate. The Court
found that the redistricting plan “satisfies the Equal Protection Clause only because on this record
it was found to have produced a distribution of legislators not substantially different from that
which would have resulted from the use of a permissible population basis.”55 Hawaii was found
to have a unique situation, wherein the significant number of tourists, military personnel, and
other transient population segments distorted the distribution of actual state citizens. The
redistricting plan that would have resulted from a total population basis would not have reflected
the true state population distribution as accurately as a state citizen population basis. Since a
registered voter population basis was the closest approximation of a state citizen population basis,
the use of the registered voter population basis was deemed consistent with the Equal Protection
Clause. However, the Court was careful to note that the ruling in the Burns case did not establish
the validity of the unique redistricting population basis for all times or circumstances.56 Although
the federal decennial census figures need not be used as the basis for state redistricting, any
alternate figures used must be shown to be the best data available or to be justified by particular
circumstances as resulting in a more accurate redistricting plan than one based on federal
decennial census total population figures.
The U.S. Supreme Court has not ruled on the constitutionality or propriety of using total
population versus voting population as the basis for intrastate redistricting in a circumstance
where the use of total population results in a disparity in voter strength in one district over
another, although there is total population equality between the districts. In Garza v. County of
Los Angeles
,57 the U.S. Court of Appeals for the Ninth Circuit held that redistricting based on
voting populations instead of the total population would have been unconstitutional. Total
population had been used as the basis of a court-ordered redistricting plan that was disputed by
the County of Los Angeles. Justice Thomas, in his dissent from a denial of a writ of certiorari in
Chen v. City of Houston,58 contrasts the decision of the Ninth Circuit in Garza with those in
which the U.S. Courts of Appeals for the Fourth and Fifth Circuits have held that the decision
about whether to use total population versus voting population as the basis for redistricting within
a state is a choice left to the legislative and political process.59
Since, under the Federal Constitution, the states arguably can and should use data other than the
official apportionment census data in their own redistricting process if they know the other data to
be the best available data, one must look at each state’s laws to determine whether the states

themselves require the use of official federal decennial census data in the redistricting processes.
Although it appears that generally states prescribe a redistricting procedure by statute for state
legislative redistricting, many do not have a statutory procedure for congressional redistricting.
The state legislatures in such states conduct the congressional redistricting on an ad hoc basis
after a federal decennial census. This means that in such states there may be no explicit statutory
requirement to use official federal decennial census data for congressional redistricting, although
there may be such an explicit requirement for state legislative redistricting. To the extent that a
state’s own laws do not explicitly require the use of official federal decennial census data for
intrastate redistricting, the state is free to use any other data.
It might be suggested that the federal government release two official sets of data, one for
apportionment of the House of Representatives among the states and the other for other purposes.
In such a situation, it could be unclear what a reference in state law to official federal decennial
census data would mean. Arguably, the second data set could still be considered official federal
decennial census data , even though not used for apportionment purposes.60 However, it should be
noted that the Court’s holding on standing for the plaintiffs in Department of Commerce v. U.S.
House of Representatives
indicates that a majority of the Court considers the references to official
federal decennial census data to be a reference to the apportionment data.61
At the time of the decision in Department of Commerce v. U.S. House of Representatives, there
was a flurry of state legislative activity concerning the type of federal decennial census data to be
used in intrastate redistricting because of the absence of sufficiently clear and explicit statutory
guidelines concerning the appropriate data to be used in intrastate congressional and state
legislative redistricting activities.62 Although there apparently has been no recent congressional
activity concerning state redistricting census data, there is a potential role for Congress in
determining what data will likely be used by the states.
Although Congress has not explicitly required states to use federal decennial census data in
congressional redistricting, it could arguably do so under the same constitutional powers which
give Congress the authority to establish other redistricting guidelines if it chooses, Art. I, § 2, cl.
1, which provides that the Members of the House of Representatives shall be chosen by the
People and Art. I, § 4, cl. 1, giving Congress the authority to determine the times, places and
manner of holding elections for Members of Congress. Where it is not clear that one data set is
more accurate than the other and the constitutional goal of equal representation is not implicated,
arguably, Congress could require that a particular type of data, including citizens only or
including aliens, must be used in congressional redistricting. However, it could not do so with
regard to the redrawing of state legislative or municipal districts, which remain the prerogative of
the states as long as no constitutional voting rights are violated.

60 The issue of what constitutes official federal decennial census data was considered during the oral arguments in the
census sampling cases. Oral Argument Transcript, found at 1998 WL 827383 on Westlaw (oral argument of Michael A.
Carvin on behalf of the appellees in No. 98-564) (discussing what data states would use if adjusted and unadjusted data

Constitutionality of Excluding Aliens from the Census: Apportionment and Redistricting

Conclusion
The Constitution requires a decennial census to determine the “actual enumeration” of the “whole
number of persons” in the United States. The data must be used to apportion the House seats
among the states, although there is no constitutional requirement it be used to determine voting
districts within the states. The term “whole number of persons” appears broad enough to include
all individuals, regardless of citizenship status, and thus would appear to require the entire
population be included in the apportionment calculation. As such, a constitutional amendment,
such as that found in H.J.Res. 111, would likely be necessary in order to exclude any individuals
from the census count for the purpose of apportioning House seats. Legislation such as the
Fairness in Representation Act (H.R. 3797 and S. 1688), which would amend the federal census
statutes to exclude aliens from the population count for apportionment purposes, would therefore
seem to be constitutionally insufficient.

Constitutionality of Excluding Aliens from the Census: Apportionment and Redistricting

Appendix. Selected Legislation to Exclude Aliens
from the Census

From time to time, Congress has considered legislation that would exclude all aliens or only
unauthorized aliens from being included in the census to apportion the House seats among the
states. Such legislation would have either amended the Census Clause of the Constitution or
enacted or amended federal census statutes.63 Generally, the legislation providing only for
statutory exclusions of aliens from the census failed because members recognized the potential
unconstitutionality of these statutory restrictions. However, Congress has also consistently not
adopted resolutions to amend the Constitution to exclude aliens, with members citing various
reasons, including the reversal of constitutional tradition.
Some proponents of excluding aliens from the apportionment census have asserted that the
framers of the Constitution did not understand the term “persons” necessarily to include aliens
and point to the first census statute in 1790, which refers to “inhabitants,” to support this
contention. Since some of the members of the first Congress had been members of the
Constitutional Convention a few years earlier, proponents argue that they must have known the
intent of the Constitutional Convention in the Census Clause and would not have enacted an
unconstitutional census statute. The proponents further argue that the term “inhabitants” in the
first census statute was understood to refer to U.S. citizens only and not to foreigners/aliens,
citing contemporaneous dictionary definitions. However, there is no direct evidence that this was
the intention and, in fact, the early censuses apparently included aliens.
The 1790, 1800, and 1810 censuses included categories for free white males, free white females,
other free persons, and slaves.64 Free white persons were categorized further by age. The 1820
census was the first to include a subcategory for “foreigners not naturalized.” Instructions to the
federal marshals conducting the 1820 census noted that the data for this subcategory was not
supposed to be added to the total data for free persons subcategorized by race and age, because
they were already included as free persons.65 These instructions appear to imply that the earlier
censuses included free foreigners as well as free citizens in the data for free persons and that the
new subcategory of information was not adding persons who would not have been counted under
existing subcategories in earlier censuses.
In 1866, Congress considered constitutional amendments that would have limited the
apportionment and census to voters or citizens. Such amendments were considered in the context
of the civil rights amendments (ultimately resulting in the Thirteenth, Fourteenth and Fifteenth
Amendments) being debated after the Civil War. The Fourteenth Amendment revised the
apportionment clause, deleting the phrase counting three-fifths of slaves and instead requiring
that the whole number of persons in each state must be counted, excluding Indians not taxed.
However, if male inhabitants who were 21 years old and U.S. citizens were disenfranchised by a
state for reasons other than participation in the Confederate rebellion or a crime, the population

63 Until 1929, the statutes implementing each decennial census were enacted prior to each census. The Census Act of
1954 superseded the 1929 statute; census legislation since 1954 has generally taken the form of amendments to the
1954 statute.

count of that state for purposes of apportionment would be reduced by the ratio of these
disenfranchised male citizens to the total number of male citizens in that state. This was intended
to discourage former slave states from disenfranchising former slaves and other African-
Americans. A similar proposal would have counted the “whole number of persons except those to
whom civil or political rights or privileges are denied or abridged by the constitution or laws of
any State on account of race or color.”66 Some versions of this type of proposal would not have
excluded Indians not taxed, while others kept the language excluding Indians not taxed.
During consideration of the civil rights amendments, an alternate type of proposal to amend the
constitutional requirements for apportionment and the census would have counted only voters in
each state to discourage former slave states from disenfranchising former slaves and other
African-Americans.67 However, this proposal was deemed flawed because it would also penalize
other states by not including aliens/non-citizens in the census count for apportionment, since
generally aliens were not permitted to vote in most states. Opponents also noted that this proposal
would depart radically from the counting of all persons required by the original census clause.
Another criticism was that suffrage would be cheapened because states would reduce or eliminate
legitimate conditions for voter eligibility in an attempt to increase the number of voters. Some
proposals to count voters or electors would have excluded citizens who had been disenfranchised
as former Confederate rebels, while others would have included such citizens. Some voter-based
apportionment census proposals were brought up for floor votes and failed.
For proponents, the type of proposals that evolved into the Fourteenth Amendment had the
advantage of not penalizing states that were not former slave states, but had high numbers of
aliens. Meanwhile, this type of legislation would still effectively discourage former slave states
from disenfranchising former slaves, since such disenfranchised persons would not be counted at
all, a significant reduction from being counted at a three-fifths ratio.
In the late 1920s and early 1930s, the issue of counting aliens was raised as Congress considered
legislation for the 1930 census and related apportionment of the House of Representatives.
Apportionment was such a contentious issue following the 1920 census that the requisite
decennial apportionment of the House of Representatives was never completed. The
apportionment had been directly legislated by Congress until the 1920 census. After the
breakdown in the process, Congress legislated a formula for calculating and allocating the
Representatives among the states, thus eliminating the partisan negotiations that had hampered
earlier apportionments and impeded/prevented apportionment in the 1920s. As Congress
considered the appropriate apportionment formula, it debated whether to amend the Constitution
to exclude aliens from the census data used for the apportionment. A 1929 Senate Legislative
Counsel opinion analyzing such proposals, concluded that “there is no constitutional authority for
the enactment of legislation excluding aliens from enumeration for purposes of apportionment of
Representatives among the States.”68 While acknowledging that no case law had ruled on the
issue of the meaning of “persons” in the Census Clause, the opinion found that according to rules
of statutory construction, “persons” had at all times been understood to include aliens.
Additionally, the reference in the Fourteenth Amendment to excluding Indians not taxed would be
unnecessary if “persons” referred only to citizens and the Fourteenth Amendment would not have

explicitly referred later in the same clause to the number of male inhabitants who were citizens
and 21 years old. With regard to the original apportionment and census language, the opinion
contrasted the use of the word “person” with the use of the word “citizen” for particular reasons
in other parts of the original Constitution. Proposals to exclude aliens by statute alone failed as
unconstitutional. Proposals to amend the constitutional language also failed.69
In 1940, when asked by a colleague whether the census for apportionment must count aliens
unlawfully present in the United States, Representative Celler asserted that a constitutional
amendment would be required to exclude even unlawfully present aliens from the census.70
Earlier congressional debates apparently do not discuss unauthorized aliens, but rather consider
the constitutionality and/or policy of excluding lawful aliens.
In the late 1970s and the 1980s, Congress considered immigration legislation that became the
Immigration Reform and Control Act of 1986, which legalized certain unauthorized aliens and
strengthened immigration laws to prevent immigration fraud, provide greater protections for
temporary foreign workers and prevent displacement of U.S. workers, etc. In the period before
and after the enactment of this legislation, Congress also considered proposals to exclude aliens
from the census, including proposals specifically to exclude unauthorized aliens.71 The latter
proposals appear to be related to the proposals to legalize or strengthen enforcement against
unauthorized aliens. Some members noted that unauthorized aliens needed to be included in the
census in order to assess the potential impact of legalization.
A key legislative proposal in the late 1980s resembled the Vitter amendment in the 111th Congress
to prohibit the use of funds to include illegal aliens in the census for apportionment of the House
of Representatives. This provision was sponsored by Senator Shelby as amendments to the bill
for appropriations to the Departments of Commerce, Justice, and State (CJS appropriations bill)72
and the Senate-passed version of the Immigration Act of 1990.73 Although such provisions were
passed by the Senate in these bills, they ultimately were not enacted. House proponents of this
proposal failed in their attempt to have the House instruct its conferees for the CJS appropriations
bill to retain the Senate provision in their negotiations;74 there had been no such provision in the
House-passed version. The House conferees objected to the provision and it was dropped.
However, the House floor debate on instructions to the conferees was echoed by the debates in
the 111th Congress.

down similar amendments for H.R. 2991 before going to conference on the bill. The conference version did not include
the Senate language; the Senate conferees agreed to deletion of this language. H. Rep’t. 101-299 at 87 (1990)
