The Twenty-Second Decennial Census

N either the E num eration C lause o f the C onstitution nor the C ensus A ct precludes the Bureau o f the
    C ensus from statistically adjusting “headcounts” in the decennial census for the year 2000 or con­
    d u cting the n o n-response follow -up on a sam ple basis.

The provision in the C ensus A ct prohibiting sam pling fo r purposes o f apportionm ent o f the H ouse of
   R epresentatives does not preclude reliance upon statistical adjustm ents that w ould im prove the ac­
   cu racy o f “head co u n t” data

                                                                                                      October 7, 1994

   You have asked, on behalf of the Department of Commerce, for our advice on
the questions w hether the use of statistically adjusted census figures would be con­
sistent with the C onstitution, U.S. Const, art. I, § 2, cl. 3, and with the Census Act,
13 U.S.C. §§ 1-307. The questions arise because the traditional method o f taking
the census fails to count a significant portion of the population, and in particular
disproportionately undercounts identifiable racial and ethnic minorities. In light of
these problem s, the Department o f Commerce is considering the use of statistical
adjustm ents in the twenty-second decennial census (for the year 2000) before the
final count is com pleted in order to improve the accuracy of that census. The De­
partm ent of Com m erce is also considering the use of sampling to conduct the fol­
low-up on households that did not respond to its initial mailing o f questionnaires.
A ccordingly, it desires to know w hether such procedures would be lawful. We
conclude that both o f the proposed changes in conducting the census would be
lawful.*

                                   The Tw enty-Second D ecennial Census

    The primary purpose of the decennial census' is to provide the basis for
Congress’s apportionment of seats in the House of Representatives am ong the
States.2 The census also serves several other legally significant objectives. His­
torically, the decennial census has been “an enumeration not only of free persons in
the States but of free persons in the Territories, and not only an enumeration of
persons but the collection of statistics respecting age, sex, and production.” L egal
Tender Cases, 79 U.S. (12 W all.) 457, 536 (1870). “The census today serves an
important function in the allocation of federal grants to states based on population.
In addition, the census also provides important data for Congress and ultimately for
the private sector.” B aldrige v. Shapiro, 455 U.S. 345, 353 (1982); see gen erally
Note, D em ography an d D istrust: Constitutional Issues o f the F ederal Census, 94
Harv. L. Rev. 841, 844-45 (1981).
     The traditional method for conducting the decennial census “is a headcount
rather than an estimation based on sampling.” Tucker v. U nited States D e p ’t o f
Com merce, 958 F.2d 1411, 1412 (7th Cir.), cert, den ied, 506 U.S. 953 (1992).3
The term “headcount” is somewhat misleading, however. “The census . . . is not a
headcount in which each and every person residing in the United States on a given
date is counted by the Census Bureau. Rather, it is a survey of the population that
through the responses of one member of each household attempts to enumerate the
entire population.” C arey v. Klutznick, 508 F. Supp. 420, 426 (S.D.N.Y. 1980),
r e v ’d, 653 F.2d 732 (2d Cir. 1981), cert, denied, 455 U.S. 999 (1982).
     In the 1990 census, the Bureau’s tabulation had four phases. First, relying on
lists compiled by commercial sources and its own fieldwork, the Bureau derived a
mailing list of as many households as it could locate. Second was the “mail
out/mail back” phase, in which the Bureau mailed out questionnaires to each
household on its list, and requested their return by April 1, 1990. (The return rate
was 63%.) The third phase was a follow-up in which the Bureau sent out another
round of mailings. The fourth phase comprised efforts by census enumerators, in
person, to contact non-responding households (or other reliable sources) to obtain
the needed information. Following that, the Bureau undertook “coverage im­
provement programs” designed to reach non-respondents in other ways, including
rechecks of all vacant or uninhabitable housing units, recanvassing of selected
blocks, an advertising campaign, checks of parolees and probationers, and a local

    1     T he first statute authorizing a census, "A n A ct providing for the enum eration o f the Inhabitants o f the
U nited S tates" (M ar I, 1790), declared that “the m arshals o f the several districts o f the U nited S tates” were
“ authorized and required to cause the num ber o f the inhabitants w ithin th eir respective districts lo be taken,”
om itting Indians not taxed. 4 N a tio n a l Stale P a p ers o f ihe U n ited States, 1789-1817, at I (Eileen Daney

to provide the census-taker “a true account, if required, to the b est o f his or her know ledge, of all and every
person belonging to [the resp o n d en t's] family ” Id at 3.

    Like earlier censuses, the 1990 census concededly did not count the entire
population of the United States.5 G iven the inherent difficulties of census-taking
and the existence o f financial and tim e constraints, some degree o f inaccuracy in
the census count is perhaps inevitable. The Bureau itself believes that “every cen­
sus has necessarily involved an undercount,” Young v. Klutznick, 497 F. Supp.
 1318, 1327 (E.D. M ich. 1980), r e v ’d, 652 F.2d 617 (6th Cir. 1981), cert, denied,
455 U.S. 939 (1982), and the courts agree that “a perfectly accurate count of up­
wards of 250 m illion people” is sim ply not “feasible.” C ity o f D etroit v. Franklin,
4 F.3d at 1377.6 Far more troubling than the bare existence of an undercount is the
fact that the 1990 census perpetuated a pattern, the existence of which has been
recognized since 1940, o f differentially undercounting African Americans.7 The
1990 census also differentially undercounted Hispanics: the estimated undercount
for that group was 5.2% , as against an estim ated undercount of 2.1% for the popu­
lation at large.8 The Bureau “specifically acknow ledge^] an undercount in the
1990 census ranging from 1.7 percent of whites to 5.2 percent of Hispanics.”9
    Despite that acknowledgement, the Secretary of Commerce declined in 1991 to
adjust the 1990 census figures to correct for the undercounts.10 The Secretary’s

decision not to make the adjustment has been the subject of litigation in three cir­
cuits, with conflicting results. Com pare Tucker (plaintiffs had no judicially en­
forceable rights) and City o f D etroit (same) with City o f N ew York (remanding with
instruction that refusal to adjust could not be upheld unless shown to be necessary
to a legitimate governmental interest).
   The Bureau is currently considering whether to adjust the “raw count” o f the
next decennial census for the year 2000. Sampling was used in connection with the
1990 census to carry out the “Post-Enumeration Survey” (the “PES”) that m eas­
ured the undercount for that year. See C ity o f N ew York, 34 F.3d at 1117; David
A. Freedman, A djusting the Census o f 1990, 34 Jurimetrics J. 99, 102-03 (1993).
In that census, the Bureau tested the accuracy of the count by a PES o f some
 174,000 households and then matching the questionnaires for households in the
PES against the same households in the census (including both mail-backs and
non-response follow-ups). The matching process provided the Bureau with data to
develop adjusting factors, or “multipliers,” to capture the estimated under- or over­
count for some 1,392 demographic subgroups. The application of the multipliers
to the enumeration data for the subgroups produced the conclusion that 1.6% of the
total population had not been counted in the census. For the 2000 census, the Bu­
reau is considering the use of a sample-based adjustment as in 1990, except that it
would complete the adjustment before its deadline for reporting State totals to the
President.
    The Bureau is also considering whether to conduct the non-response follow-up
on a sample basis, rather than sending enumerators to each non-responding house­
hold. Specifically, it is proposing to contact, by telephone or in person, between
25% and 50% of the households that failed to return the census questionnaire. The
Bureau would then extrapolate from the results of this sample to estimate the whole
non-respondent population. The Bureau believes that the use of this procedure
would save it between $300 and $600 million. At the same time, it advises us that
the procedure would also produce greater accuracy than was achieved in the 1990
census.
    In the past, the Bureau took the position that it would be legally precluded from
adjusting the census for apportionment purposes. See Census U ndercount A d ju st­
ment: B asis f o r D ecision, 45 Fed. Reg. 69,366, 69,371-73 (1980). This claim was
based on both constitutional and statutory grounds. First, the Bureau has argued
that

        interpretation o f the phrase “actual enum eration” in Article 1, Sec­
        tion 2, Clause 3 must begin with the words themselves, and that the
        term s “census” and “enumeration” mean nothing more or less than a
        headcount. [It] say[s] that the use of the m odifier “actual” with the
        word “enum eration” can only reinforce the conclusion that the
        fram ers o f the Constitution intended a headcount, and nothing but a
        headcount. [It] further reifies] upon the fact that, with the exception
        o f the 1970 census when imputations were performed which added
        approxim ately 4.9 million people, the census has been, since 1790,
        an actual headcount and nothing more.

Young v. K lutznick, 4 91 F. Supp. at 1332. The Bureau has also argued in the past
that “even if the Constitution does not prohibit an adjustment for apportionment of
Representatives, C ongress has by statute prohibited such an adjustment.” Id. at
 1334. W e consider these issues in turn.

                                                II.

   The Enum eration Clause of the Constitution reads in relevant part as follows:

        R epresentatives . . . shall be apportioned among the several States
        . . . according to their respective N um bers . . . . The actual Enu­
        meration shall be made within three Years after the first Meeting of
        the Congress of the United States, and within every subsequent
        Term o f ten Years, in such M anner as they shall by Law direct.

U.S. Const, art. I, § 2, cl. 3; see a lso U.S. Const, amend. XIV, § 2
(“R epresentatives shall be apportioned among the several States according to their
respective numbers, counting the w hole num ber o f persons in each State . . . . ”).
    The Enum eration Clause was one facet of the “Great Com prom ise” at the Con­
stitutional Convention, which provided for equal representation of the States in a
Senate, and representation of “the People of the several States” in a House of Rep­
resentatives. U.S. Const, art. I, § 2, cl. 1; see gen era lly W esberry v. Sanders, 376
U.S. 1, 10-16 (1964); D em ography an d D istrust, 94 Harv. L. Rev. at 846. Be­
cause the Fram ers “intended that in allocating Congressmen the number assigned
to each State should be determined solely by the number of the State’s inhabitants
. . ..[t]he C onstitution embodied Edm und R andolph’s proposal for a periodic cen­
sus to ensure ‘fair representation o f the people’” W esberry, 376 U.S. at 13-14
(citations omitted).
    Before the first decennial census in 1790, no modern Nation had undertaken a
census (although all the States of the United States, with some exceptions in the
South, had done so). See Hyman Alterman, Counting P eople: The Census in

H istory 164 (1969). Thus, when the Framers were apportioning seats in the first
House of Representatives, their decisions were the outcome of “conjecture and
political compromise: [they] apparently assigned some of the smaller States a
number of Representatives not justified by the size of their populations.” M em o­
randum for Wendell L. W ilkie II, General Counsel, Department o f Commerce,
from Stuart M. Gerson, Assistant Attorney General, Civil Division at 4 (July 9,
1991) (the “Gerson M em orandum ”).11 The C onstitution’s reference to an “actual
Enumeration” must be explained by reference to the Fram ers’ ignorance of the
exact size of the population and its distribution among the States: “[w]hen the
Constitution speaks of actual enumeration, it speaks o f that as opposed to esti­
m ates.’’ Young v. Klutznick, 497 F. Supp. at 1332 (emphasis added). A cco rd

P opulation D ata at 2 (Sept. 25, 1980) (the “Harmon M em orandum ”) (“the phrase
[‘actual Enum eration’] was chosen because an accurate population count was es­
sential once the Convention decided, in the Great Compromise, that representation
in the House would be apportioned on the basis of population.”).
    The proposal for a periodic enumeration of the population originated, as noted
above, with Edmund Randolph, as an incident to the Great Compromise. On July
 10, Randolph moved a proposal calling for Congress “to cause a census, and esti­
mate to be taken within one year after its first meeting; and every [left blank] years
thereafter — and that the L egislature] arrange the Representation accordingly.”
James Madison, N otes o f D ebates in the F ederal Convention o f 1 7 8 7 , at 265
(Adrienne Koch ed., 1966) (bracketed material added). George M ason spoke in
favor of the motion on the next day, declaring that “[h]e did not object to the con­
jectural ratio which was to prevail in the outset; but considered a Revision from
time to time according to some permanent & precise standard as essential to [the]
fair representation required in the [first] branch.” Id. at 266. Later in the debate,
Randolph repeated M ason’s point that “the ratio fix[ed] for the [first] meeting [of
Congress] was a mere conjecture.” Id. at 267. On August 21, Madison repeated
that “[t]he last apportionment o f Cong[ress], on which the number o f Representa­
tives was founded, was conjectural and meant only as a temporary rule till a Cen­
sus should be established.” Id. at 497. Madison also explained in The F ederalist
that the provision in Article I, Section 2, Clause 3 of the Constitution for a House
o f Representatives that would consist of sixty-five members in the First Congress
was merely “a temporary regulation,” to be revised when the findings o f the census

R ossiter ed., 1961).12
    These discussions make it clear that, in requiring an “ actual ” enumeration, the
Framers m eant a set o f figures that was not a m atter of conjecture and compromise,
such as the figures they had themselves provisionally assumed. An “actual” enu­
meration would instead be based, as George M ason put it, on “some permanent &
precise standard.” There is no indication that the Framers insisted that Congress
adopt a “headcount” as the sole m ethod for carrying out the enumeration, even if
later refinem ents in the metric of populations would produce more accurate meas­
ures.
    Furtherm ore, the Fram ers left it to Congress to conduct the enumeration “in
such M anner as they shall by Law direct.” U.S. Const, art. I, § 2, cl. 3. That ex­
plicit delegation im plies that the Fram ers were w illing to allow for innovation in
the choice o f m easuring techniques; and, not surprisingly, “the Census Bureau’s
unbroken historical practice really has been to use modern knowledge and scien­
tific techniques to get further and further away from simple headcounting.” Young
v. K lutznick, 497 F. Supp. at 1333.13 “The result, and not the method, is the im­
portant lesson of the historical experience.” Harm on Memorandum at 2.
    In addition, Article I, Section 2, Clause 3 o f the Constitution was amended by
section 2 o f the Fourteenth Amendment. Section 2 declares that “Representatives
shall be apportioned am ong the several States according to their respective num­
bers, counting the whole number o f persons in each State, excluding Indians not
taxed.” U.S. Const, amend. XIV, § 2. Further, section 5 confers on Congress the
“power to enforce, by appropriate legislation, the provisions of this article.” Id.
§ 5. C ongress’s powers under section 5 have been “equated . . . with the broad
powers expressed in the Necessary and Proper Clause, U.S. Const, art. I, § 8, cl.
18. ‘Correctly viewed, § 5 is a positive grant o f legislative power authorizing
Congress to exercise its discretion in determ ining whether and what legislation is

determ ine how to carry out the apportionm ent called for by section 2, and to con­

It would be strange indeed to suppose that Congress — or its delegate, the Bureau
— lacked the power to authorize a statistical adjustment that would correct the
persistent and acknowledged undercounting of African Americans in that enu­
meration, particularly in view of the fact that the Fourteenth Amendment was pri­
marily intended for the protection of that class. See S trauder v. W est Virginia, 100
U.S. 303, 306(1880).
    Finally, constitutional plaintiffs injured by the decision to use adjusted census
data for apportionment might argue that so sharp a departure from the B ureau’s
longstanding practices was unjustified.14 See Senate o f California, 968 F.2d at 978
(“the method by which the Secretary is to do the count . . . is generally expected to
be a head count”); see a lso Seventeenth D ecennial Census, 41 Op. A tt’y Gen. at 34
(if the Director “has consistently followed the practice in question over a long pe­
riod of time, and it has not been challenged in the Congress or elsewhere . . . his
interpretation ought not to be disturbed except for very weighty reasons”) .15 It
could be contended that the use of unadjusted “headcounts” almost invariably since
the first census of 1790 represents a practical construction of the Enumeration
Clause which the Executive, at least absent weighty reasons, may not reverse. See,
e.g., Smiley v. Holm, 285 U.S. 355, 369 (1932) (“long and continuous interpreta­
tion in the course of official action under the law may aid in removing doubts as to
its meaning. This is especially true in the case o f constitutional provisions gov­
erning the exercise of political rights . . . .”); The P ocket Veto Case, 279 U .S. 655,
688-90 (1929). W e believe, however, that the change in the Bureau’s policy would
be upheld against an attack of this nature if there were adequate proof that statisti­
cal adjustments would be feasible and would generate more accurate counts o f both
the total population and of minorities.
    Thus, in Franklin v. M assachusetts, the Court upheld the Bureau’s changed
policy of allocating overseas government personnel to the several states for resi­
dence purposes for the 1990 census. The Court stated that

           the Secretary of Commerce made a judgm ent, consonant with,
           though not dictated by, the text and history of the Constitution, that
           m any federal employees tem porarily stationed overseas had retained
           their ties to the States and could and should be counted toward their
           S tates’ representation in C ongress . . . . The Secretary’s judgm ent
           does not ham per the underlying constitutional goal of equal repre­
           sentation, but, assuming that employees temporarily stationed
           abroad have indeed retained their ties to their home States, actually
           prom otes equality.

   In the present case, the validity o f the policy change would turn largely on the
evidentiary showing that the use o f statistical adjustments will produce a more ac­
curate count of the population than the bare “headcount” data alone. It appears to
us that the factual predicate for the change to adjusted figures is adequate. As the
Second Circuit pointed out, the district court in C ity o f N ew York found “that the
PES-indicated statistical adjustment was feasible; that for most purposes and for
m ost of the population that adjustment would result in a more accurate count than
the original census; and that the adjustm ent would lessen the disproportionate un­
dercounting of m inorities.” City o f N ew York , 34 F.3d at 1129. Assuming that
sim ilar findings would hold true for the next decennial census, then we see no rea­
son why the Bureau, in the exercise o f its expertise and discretion, may not alter its
past practice and adjust the census figures it obtains through a “headcount.” 16
   A ccordingly, we conclude that the Constitution does not preclude the Bureau
from em ploying technically and administratively feasible adjustment techniques to
correct undercounting in the next decennial census.

                                                         III.

   The Census A ct includes two provisions authorizing the use of statistical meth­
ods, including “sam pling,” in conducting its statutory responsibilities. The first
statute, 13 U.S.C. § 141(a), states that

          [t]he Secretary shall, in the year 1980 and every 10 years thereafter,
          take a decennial census of population as o f the first day of April of
          such year, which date shall be known as the “decennial census
          date”, in such form and content as he may determine, including the
          use of sam pling procedures and special surveys.

                                   The Tw enty-Second D ecennial Census

  The second statute, 13 U.S.C. § 195, authorizes, indeed mandates, the use of
sampling, but with a limitation relating to apportionment

          [e]xcept for the determination of population for purposes o f appor­
          tionment of Representatives in Congress among the several States,
          the Secretary shall, if he considers it feasible, authorize the use of
          the statistical method known as “sam pling” in carrying out the pro­
          visions of this title.

    In the past, the Bureau has taken the position that § 195 prohibits statistical ad­
justm ent of census data for purposes of apportionment. The difficulty centered on
 § 195’s prohibition on the use of “sampling” in determining the size o f the popula­
tion for purposes of apportionment. Since the scope of § 195’s exception is not
plain from the language of the statute, we turn to the legislative history of that sec­
tion.
    Congress enacted § 195 in 1957, but in a form that authorized, rather than re­
quired, the use of sampling; a 1976 amendment transformed the Secretary’s
authorization into the conditional mandate of the current statute.17 The enacting
Congress of 1957 considered § 195 to be merely a change “of an administrative
 nature” that was “needed for the timely and efficient performance of the biggest
jobs the Bureau of the Census has ever undertaken.” S. Rep. No. 85-698, at 2
 (1957), reprinted in 1957 U.S.C.C.A.N. 1706, 1707. The proviso gave the Bureau
 the “authority to use sampling in connection with censuses except for the determ i­
 nation of the population for apportionment purposes.” Id. at 3, rep rin ted in 1957
U.S.C.C.A.N. at 1708.
    W hat Congress originally meant by “sam pling” is not clear. In testimony in
 support of the 1957 legislation, Robert W. Burgess, the Director o f the Bureau of
 the Census, explained that

          [t]he use of sampling procedures would be authorized by the pro­
          posed new section 195. It has generally been held that the term
          “census” implies a complete enumeration. Experience has shown
          that some of the information which is desired in connection with a
          census could be secured efficiently through a sample survey which
          is conducted concurrently with the complete enumeration o f other
          items; that in some instances a portion of the universe to be in­
          cluded might be efficiently covered on a sample rather than a com ­
          plete enumeration basis and that under some circumstances a
          sample enumeration or a sample census might be substituted for a

     17      As enacted in 1957, the statute had stated that "[e]xcept for the determ ination o f population for appor-
tionm ent purposes, the Secretary m ay, w here he deem s it appropriate, authorize the use o f the statistical
m ethod known as 'sam p lin g ' in carry in g out the provisions o f this title “ Pub L N o 85-207, § 14, 71 Stat

        full census to the advantage of the Government. This section, in
        com bination with section 193, would give recognition to these facts
        and provide the necessary authority to the Secretary to permit the
        use o f sam pling when he believes that it would be advantageous to
        do so.

8 (1 9 5 7 ).
    The D irector’s testim ony suggests that in enacting § 195, Congress intended
that the Bureau conduct a “complete enum eration” or a “full census” when deter­
mining the size of the population for apportionment purposes, but that the Bureau
could use “sam pling” in other contexts, where a “sample enumeration” or a
“sample census” might be used “to the advantage o f the G overnm ent.” Read in the
light o f the testimony, the statute’s preclusion o f “sam pling” need not have meant
that statistical adjustm ent o f census figures was forbidden: Congress may well
have intended only that the decennial census not be a “sample census.” Moreover,
a “com plete enum eration” or “full census” may affirmatively require statistical
adjustm ents o f “headcount” data to be made.
    O ur Office has previously argued that the 1957 legislative history should not be
understood to preclude statistical adjustm ent. Citing the testimony quoted above,
we argued that “ [sjam pling refers to a representative portion of the whole . . . while
adjustm ent refers to additions to the whole, here the headcount. As we read the
Census Act, there is no statutory prohibition o f statistical adjustm ent.” Harmon
M em orandum at 3 (citation omitted). The Congressional Research Service (the
“CRS”), however, reviewed the same testimony and drew a contrary inference:

        it appears that when Section 195 was originally enacted, the De­
        partm ent of C om m erce took the position that an actual enumeration
        was required for all decennial census purposes. Section 195 was
        enacted in order to relieve this restriction for purposes other than
        apportionm ent by sanctioning the use o f sampling when appropri­
        ate. There was no need to m ention other forms o f estimating popu­
        lation since this section was making an exception to the general
        requirem ent o f an actual enumeration only for sampling. Therefore,
        one may conclude that Section 195 was not intended to sanction the
        use o f m ethods o f estimating population other than “sampling,” and
        did not intend to permit the use of this method for purposes of ap­
        portionment.

   The 1976 legislation amending the Census Act, Act of Oct. 17, 1976, Pub. L.
No. 94-521, 90 Stat. 2459, 2464, was primarily concerned with the establishment
of mid-decade censuses. In carrying forward (and amending) § 195, we believe
that Congress meant that while reliance on sampling alone might be appropriate or
desirable for mid-decade censuses, it should not be the exclusive procedure for
tabulating the population in decennial censuses.18 So understood, the 1976 re­
enactment does not bar the statistical adjustment of the decennial census if such
adjustments would improve their accuracy.
   This interpretation of the 1976 legislative history is not uncontroverted. See
Gerson M emorandum at 11 (“C ongress’ amendment of Section 195 in 1976 is
similarly open to two alternative interpretations.”). The CRS, noting that both the
Com ptroller General and the Bureau had advised Congress in 1976 o f ongoing
developments in estimating or allocating populations other than sampling, argued
that “it would be logically inconsistent for Congress to prohibit sampling for pur­
poses o f reapportionment, but at the sam e time to permit the use of other tech­
niques whose reliability had not yet been determ ined.” Joint Hearing at 188.
Based on its review of the legislative history, CRS concluded that “the use o f
demographic estimates for purposes of apportionment of Representatives among
the States . . . is prohibited by Section 195 of Title 13.” Id. at 192.19
   In our judgm ent, the better view is that the Census Act does not preclude the
Bureau from engaging in statistical adjustments o f the next set of decennial census
figures. See Franklin v. M assachusetts, 505 U.S. at 820 (Stevens, J., joined by

     18 The S enate Report stated that the section o f the 1976 legislation that m odified 13 U S.C. § 195 '“differs

ment) (Census A ct “em bodies a duty to conduct a census that is accurate and that
fairly accounts for the crucial representational rights that depend on the census and
the apportionm ent”). A non-preclusive reading gives due weight to the fact that,
when it re-enacted § 195 in 1976, C ongress was primarily concerned with institut­
ing m id -d eca d e censuses. Its prohibition on “sam pling” in decennial censuses ap­
pears to have m eant only that while a procedure relying on “sampling” alone might
be the m ost cost-effective means to discover the information sought in a mid­
decade census, the Bureau should not rely on “sam pling” as its exclusive method of
tabulating population figures in the decennial census. The use o f sampling tech­
niques in the m id-decade census is “probably a pragmatic necessity in that in­
stance, given the vast mobilization of people and resources needed to conduct an
even som ew hat accurate head count.” Senate o f California, 968 F.2d at 978. De­
spite the additional costs entailed, however, Congress did not wish the decennial
census to consist o f “a mere statistical m anipulation through the use of sampling
and other techniques.” Id. Nothing in amended § 195 p ro sc rib e d the use o f sam­
pling or other statistical devices in connection with the decennial “headcount,”
however, if such adjustm ents would result in a more accurate tabulation.
    Furtherm ore, in adopting the Census Act, Congress “left the actual administra­
tion o f a great num ber o f necessary details to the judgm ent and discretion of the
D irector o f the Census.” Seventeenth D ecennial Census, 41 Op. A tt’y Gen. at 33.
Standing alone, § 141(a), which authorizes the D irector to take the decennial cen­
sus “in such form and content as he may determine, including the use of sampling
procedures and special surveys,” w ould seem to permit statistical adjustments, if in
the D irector’s judgm ent they would produce greater accuracy. W hile § 195 un­
doubtedly m akes an exception for the use of sampling in apportionment, that ex­
ception can be construed narrowly, as befits C ongress’s otherwise broad delegation
of pow er to the Bureau: the section could be taken to mean that while census fig­
ures used for apportionm ent may not be based on sampling alone, it is permissible
to use population sam ples as one elem ent in a more complex operation by which a
prior “headcount” is corrected. Such a reading has in fact generally been adopted
by the courts. See C arey v. Klutznick, 508 F. Supp. at 415; Young v. Klutznick,
497 F. Supp. at 1334-35; see also Gerson M em orandum at 18 (“the weight o f ex­
isting caselaw ” is “that Section 195 does not preclude statistical adjustment”).20
    M oreover, if § 195 were read as preclusive, its constitutionality would be highly
suspect. Because (as shown above) a non-preclusive reading is a reasonable one, it
should be preferred.
    Substantial constitutional issues would arise under both the Enumeration Clause
and the Fifth A m endm ent if § 195 were construed to prevent the Bureau from ad­

justing census data for apportionment. The Enumeration Clause prescribes that
Representatives be apportioned to the several States “according to their respective
Numbers,” and it can be argued that the Clause is violated if Representatives are
apportioned on the basis of a census count that is known to be deficient, but that
could be rendered more accurate by feasible adjustments. See Franklin v. M a ssa ­
chusetts, 505 U.S. at 806 (Bureau’s decision to allocate government personnel sta­
 tioned abroad to State designated as home of record “does not ham per the
 underlying constitutional goal o f equal representation, but . . . actually promotes
equality”); United States D e p ’t o f Com m erce v. M ontana, 503 U.S. 442, 461
(1992) (Court “might well find” that requirement that Representatives be appor­
tioned by reference to the populations o f the several States “em bodied] the same
 principle of equality” as found in W esberry), C arey v. Klutznick, 508 F. Supp. at
414 (language of Enumeration Clause evinces “an intent that apportionment be
based on a census that most accurately reflects the true population of each state”);
cf. W esberry, 376 U.S. at 13-14.
    Furthermore, “[t]he Fifth Amendment . . . might be thought, by analogy to the
decisions invalidating the malapportionment of state legislatures under the equal
protection clause, to require the federal government to apportion congressional
seats . . . in accordance with an accurate estimate of the number of people in each
state.” Tucker, 958 F.2d at 1414. See, e.g., R eynolds v. Sims, 377 U.S. 533, 555
(1964) (“the right of suffrage can be denied by a debasement or dilution of the
weight of a citizen’s vote just as effectively as by wholly prohibiting the free exer­
cise of the franchise”). Thus, the Second Circuit has found that the B ureau’s deci­
sion not to adjust the 1990 census figures was constitutionally suspect under the
Fifth Amendment:

        are factors that traditionally require that the governm ent’s action be
        given heightened scrutiny: the right to have one’s vote counted
        equally is fundamental and constitutionally protected, and the un­
        adjusted census undercount disproportionately disadvantages cer­
        tain identifiable minority groups. . . . That the goal o f precise
        equality cannot be achieved nationwide . . . does not relieve the fed­
        eral government of the obligation to make a good-faith effort to
        achieve voting-power equality “as nearly as is practicable.”

    We need not here consider whether the Second C ircuit’s view of the merits is
correct; nor need we address the issue whether the question the court decided was
litigable. Suffice it to say that there would be substantial constitutional difficulties
under both the Enumeration Clause and the Fifth Amendment if § 195 were under­
stood to prohibit the Bureau from making practicable statistical adjustments that
would result in a more accurate tally than the traditional headcount. Section 195

                          Opinions o f the O ffice o f L egal C ounsel

should be construed, if ‘“ fairly possible,’” to avoid those difficulties. See, e.g.,
A sh w an der v. TVA, 297 U.S. 288, 348 (1936) (Brandeis, J., concurring) (citation
omitted). Because a constitutionally unproblematic reading is justified (and has, in
fact, been adopted by m ost courts), it should be adopted.
   A ccordingly, § 195 does not preclude reliance upon technically feasible statisti­
cal adjustm ents to improve the accuracy of “headcount” data, and specifically to
correct the differential undercounting of minority group populations. It also does
not prohibit the Bureau from conducting the non-response follow-up on a sample
basis, rather than sending enumerators to every non-responding household, where
the use o f the form er technique would improve accuracy while substantially low­
ering adm inistrative costs.

                                       Conclusion

   N either the Constitution nor the Census Act precludes the Bureau from making
the proposed statistical adjustments o f “headcount” data in the decennial census for
the year 2000.
