Ever since the founding fathers authorized a national headcount as the
means of apportioning seats in the federal legislature, the decennial census
has been a political battleground. Political power, and more recently the
allocation of federal resources, depend directly upon who is counted and
who is left out. Who Counts? is the story of the lawsuits, congressional
hearings, and bureaucratic intrigues surrounding the 1990 census. These
controversies formed largely around a single vexing question: should the
method of conducting the census be modified in order to rectify the
demonstrated undercount of poor urban minorities? But they also stemmed
from a more general debate about the methods required to count an ever
more diverse and mobile population of over two hundred million. The
responses to these questions repeatedly pitted the innovations of
statisticians and demographers against objections that their attempts to
alter traditional methods may be flawed and even unconstitutional.
Who Counts? offers a detailed review
of the preparation, implementation,
and aftermath of the last three censuses. It recounts the growing criticisms
of innaccuracy and undercounting, and the work to develop new
enumeration strategies. The party shifts that followed national elections
played an increasingly important role in the politization of the census, as the
Department of Commerce asserted growing authority over the scientific
endeavors of the Census Bureau. At the same time, each decade saw more
city and state governments and private groups bringing suit to challenge
census methodology and results. Who Counts? tracks the legal course that
began in 1988, when a coalition led by New York City first sued to institute
new statistical procedures in response to an alleged undercount of urban
inhabitants. The challenge of accurately classifying an increasingly mixed
population further threatens the legitimacy of the census, and Who Counts?
investigates the difficulties of gaining unambiguous measurements of race
and ethnicity, and the proposal that the race question be eliminated in favor
of "ethnic origin." Who Counts? concludes with a discussion of the
proposed census design for 2000, as well as the implications of population
counts on the composition and size of Congress. This volume reveals in
extraordinary detail the interplay of law, politics, and science that propel the
ongoing census debate, a debate whose outcome will have a tremendous
impact on the distribution of political power and economic resources among
the nation's communities.

Excerpts from Reviews of Who Counts?
It is manifestly impossible to conduct a complete and accurate count
of several hundred million people.
The issue is not only how to produce the most complete and acurate count possible but also how
the inevitably imperfect result should be reported.
From The Journal of Official Statistics, Vol. 16, No. 2, 185-190, by Milorad S. Kovacevic
The bookis a unique and rich melange of historical facts
and data, reviews of statistical
methods and concepts, newspaper reports and commentaries, excerpts from the lawsuit
filings, expert tstimonies, and court rulings. The authors, although participants in some
of the events surrounding the 1990 and 2000 censes[es], are trying to unfold the story in
a neutral and a nonjudgemental way. ...[O]verall, the book represents an excellent
review of events that marked census-taking in the second half of the twentieth century
It is refreshing to read a book in which a bureaucratic organization
is not portrayed as bungling and incompetent. Indeed the Census
Bureau, though occasionally falling victim to `computer errors,'
appears commendably thorough in its planning, consulting widely with
outside experts before implementing new procedures. The bad guys are
rather more stereotypical-politicians, and Republican politicians at
that, putting narrow party interests before the wider good.
Of course, this is far from being a simple issue, and some senior
statisticians have argued against adjustment. The reader will need to
look elsewhere for the very detailed technical arguments, but the book
does an excellent job of making the essential issues accessible to
non-specialists. It is also a surprisingly entertaining story, and
one that is fully accessible to non-American readers.
As a non-American who has been following some of the
developments in the U.S., I found the book gave a wonderful, clear
exposition of the issues and current situation. Statisticians not
familiar with these controversies will find the material both curious
and fascinating. Those who have more familiarity will find that this
book provides a useful summary of this complex situation.
This book combines Margo Anderson's background as a social
historian and Stephen Fienberg's background in statistical methodology
to create a unique narrative and commentary.
. . . For each of the last several U.S. censuses, members of minority groups have been
missed about five percent more often than whites. Margo J. Anderson and Stephen E.
Fienberg, in their new book Who Counts?, provide an important contribution to the ongoing
discussion on how to address this persistent "differential undercount." . . .The two
have joined forces and achieved their goal of writing a narrative that provides context and
perspective for future debates.
. . . . . .
The authors provide a concise, yet richly informative, history of the
Readers learn how, in contrast to the analogous figure for whites, the number of black males who
registered for the armed services in the fall of 1940 far exceeded estimates based on the 1940 census.
They learn how professional statisticians, both career employees of the Census Bureau and members of
outside review panels, have overseen innovation in the census. They learn how large cities and other
parties angered by disproportionate undercounts have aired their cases in the federal courts, which have
taken their grievances seriously. And they learn how politics inevitably interacts with census-taking,
because of the direct political implications of census results and because politicians have increasingly
recognized that the jockeying for position on the next census begins early in the 10-year census cycle.
Anderson and Fienberg provide similarly concise and helpful reviews
of dual-system estimation . . .
and of the political context of the debate over possible adjustments to the 1990 census. They describe
the legal wrangling surrounding the 1990 Census, particularly the case of City of New York, et al. v.
U.S. Department of Commerce, et al., in which Fienberg testified. After considering expert testimony f
rom both sides, a federal district court judge decided that, although he personally would probably have
opted for adjustment, he could not find the decision against adjustment by then Secretary of Commerce
Robert A. Mosbacher to be "arbitrary and capricious." A federal appeals court overruled this decision on
a 2-1 vote, claiming that the standard for review should be whether the plaintiff's constitutional rights
had been violated. The district court ruling, however, was reinstated by a 9-0 Supreme Court decision
that supported the stronger arbitrary-and-capricious standard of review. In their critique of the Supreme
Court opinion written by Chief Justice William Rehnquist, Anderson and Fienberg note inaccuracies in its
discussion of statistical adjustment methods. Their comments serve as a good example of the colorful
material in the book and provide a cautionary tale regarding the risk of leaving all decisions about
census-taking to nonscientists.
The authors take aim at several "myths" about census adjustment, which
they introduce in a prologue
that is not easy to follow without knowing the scientific and political context. Their point is well taken,
however, that many criticisms of statistical adjustments are based on misunderstandings or
misrepresentations. Overall, the authors' short course in the facts and logic underlying adjustments
succeeds in dispelling the myths they cite. . . . [They] deserve particular credit for their discussion of
racial and ethnic classifications in the census, especially the recent modification that allows respondents
to identify themselves as belonging to one or more ethnic categories. They note that, with conventional methods,
reliable estimates of undercount rates require the definition of fairly sizable poststrata. Thus efforts to eliminate
ethnic classification, or to block the grouping of individuals with similar demographic characteristics, conflict
with efforts to correct for differential undercount. The authors provide an excellent treatment of this concern,
and their book seems to be the first to address the issue.
Anderson and Fienberg omit a number of technical details in exchange
for brevity and simplicity. But they
successfully avoid inflammatory rhetoric and offer a wealth of insight. For those interested in understanding
the historical and scientific context of the census adjustment controversy, Who Counts? is absolutely essential
To see the complete review by Belin,
Who Counts? is well-organized, full of interesting material,
and clearly written. It is accessible to
students as well as professionals. It should be of interest to any one interested in censuses,
population statistics, and issues at the nexus of statistics and politics. I suspect that the authors
would be pleased if American journalists, lawyers, and members of Congress, many of whom have
misconstrued the recent issues (sometimes deliberately) would read this book.
. . . .Margo J. Anderson and Stephen E. Fienberg's [new book,]Who Counts?, [is]
invaluable to anyone interested in the politics of the census, reapportionment and
redistricting. Those issues will be in the courts throughout the next decade. The redistricting
lawsuits will challenge district lines from congressional seats to commissioner court
precincts. (Anderson's earlier book on the census was cited in Supreme Court opinions on
both sides of the issue earlier this year.)
The most contentious census issue before Congress
is the use of a sampling technique for
apportionment purposes. The issue burst into the national news in the summer of 1997 when
Republican congressmen amended a bill providing flood relief in the Dakotas to prevent
sampling. President Clinton vetoed the bill.
Advocates of sampling argue that it will reduce the
undercount of minorities, an increasingly
pernicious legal problem because of its implications for civil rights and federal aid. Congress
has authorized sampling for the distribution of federal aid to the states but not for
Opponents of sampling argue that it is an unscientific
technique that will allow the Census
Bureau discretion to manipulate the numbers in favor of Democrats. (One of the authors' best
contributions to the debate is a list of myths put forward by sampling opponents.)
So there may be two sets of numbers -- one for reapportionment,
another for federal aid and
Congress reapportions. State legislatures redistrict.
Which figures will legislatures use to
redistrict? The Census Bureau sensibly wants to produce a single set of numbers, and that is
the recommendation of Anderson and Fienberg.
Census issues have been much litigated during the
past decade. The result is a superb legal
and historical record of the various disputes and the arguments put forth by each side and the
actions taken by the various players: President Clinton, members of Congress, the secretary
of commerce, Census Bureau officials, state and local government officials, and federal judges.
Who Counts? makes that record readily accessible.
It will become the handbook for those
(Also available at: http://www.swt.edu/cpm/corner/whocounts.html
The book begins with a history of the Census. The story starts with
the founding fathers' establishing
a representative form of government that required a census to make it work. We learn that the political
problems we face today with the census have been with us from the very beginning: Who should be
counted? How should they be counted?
This book will be read by science writers, lawyers, judges and politicians
as the inevitable court cases
for the census 2000 approach. We hope that people who read this book will come away with the feeling
that there has to be a better way than fighting it out in the courts to figure out how to carry out this
important and challenging statistical task.
The U.S. Census in the News
Commerce Secretary Chooses Unadjusted Census Data After
Recommends Against Statistical Correction
Expert Panel Cites Lack of Time To Complete Analysis;
Confirms Net and Differential
Undercounts in Census 2000
March 14, 2001 (prepared by Census 2000 Initiative )
Relying on advice from a Census Bureau committee established last fall
under a federal rule
issued by his predecessor, Secretary of Commerce Donald Evans last week decided to
release unadjusted census population counts to the states for "the purpose and only the
purpose of redistricting." The Secretary said in his March 6th announcement that he
followed an "open, reasonable and fair" process and "took full account of the views of
On March 1, a committee of twelve senior Census Bureau professionals
release of unadjusted census numbers to the states for redistricting purposes. Acting
Census Bureau Director William Barron Jr., who as the agency's Deputy Director also
serves on the Executive Steering Committee for A.C.E. Policy (ESCAP), transmitted the
recommendation, in which he concurred, and accompanying report to Secretary of Commerce
Donald Evans. In accepting the report's findings, the Secretary called the recommendation
"correct and prudent." He also praised the Bureau's staff, saying, "You set ambitious goals
and you exceeded them."
"We have achieved a quality count," Secretary Evans said, calling
Census 2000 "the most
accurate census ever," with "the lowest undercount [and] the smallest differentials in
history by far." Based on the results of its Accuracy and Coverage Evaluation (A.C.E.)
survey, the Census Bureau reported a net national undercount of 1.2 percent, or 3.3 million
people. It has not yet reported the total numbers of people missed (omissions) and counted
twice or wrongly included (erroneous enumerations), which offset each other to calculate
the net national undercount. The net undercount in 1990, measured by a similar though
smaller quality-check survey, was 1.6 percent, or 4 million people. The Bureau reported an
undercount of 1.2 percent, or 2.8 million people, in the 1980 census, based on its independent
demographic estimate of the population.
In its recommendation, the ESCAP concluded that "there is considerable
support the use of adjusted data, and that Census 2000 and A.C.E. operations were well
designed and conducted." However, the committee said it was "unable to conclude, based on
the information available at this time, that the adjusted Census 2000 data are more accurate
for redistricting." Further research, the panel said, is "likely" to show that "adjustment based
on the A.C.E. would result in improved accuracy," and to confirm that Census 2000 reduced
but did not eliminate a net national undercount and a "differential" undercount of minorities,
renters, and children.
Dr. Barron noted in his memorandum of transmittal that the "primary
reason" for the
conclusion is the "apparent inconsistency in population growth over the decade as estimated
by the A.C.E. and demographic analysis." The committee could not explain the differences,
which "raise[s] the possibility of an unidentified error in the A.C.E. estimate or Census
2000," in the time available, he said. The demographic analysis figures are "significantly
lower" than the population as measured by the A.C.E. survey, the committee said. A.C.E. is
the Accuracy and Coverage Evaluation program, which included a quality-check survey of
314,000 households designed to measure under- and overcounts in the census. Demographic
analysis is an independent estimate of the nation's population the Bureau produces based
primarily on birth, death, immigration, emigration, and Medicare records.
The ESCAP described the results of "quality measures" designed to evaluate
accuracy of the adjusted and unadjusted numbers. It concluded that while "the adjusted data
are more accurate overall," it had concerns that merited further research, including a
possibility that the unadjusted data for counties with populations below 100,000 were more
accurate. The ESCAP report and recommendation are posted on the Census Bureau's web
site at www.census.gov/dmd/www/escapreport.html.
Considerable controversy has followed the decsion by the Bureau to recommend
the use of unadjusted data
for release as part of the PL 94-171 file, which is used for redistricting by the states, among other uses.
The Democratic and Republican members of the U.S. Census Monitoring Board have issued separate reports,
that are available on their websites: http://www.cmbp.gov/ and http://www.cmbc.gov/, respectively.
