Preface
The Panel to Review the 2000 Census was established in 1998 by the Committee on Na-
tional Statisticsof the National ResearchCouncil at therequest of the U.S. Census Bureau. The
panel hasa broad charge toprovide anindependentassessmentof thequalityof the2000 census
operations and results. It is charged in particular to review the statistical methods of the 2000
census, including the use of the Accuracy and Coverage Evaluation (A.C.E.) Program and dual-
systems estimation(DSE), along with other census procedures that may affect the completeness
and quality of thedata.
As part of its work, the panel held three open workshops on topics related to the A.C.E. and
possible adjustment of the census counts for population coverage errors. The panel has prepared
proceedings of each workshop to be part of the public documentation of planning for the 2000
census.
The first workshop was held October 6, 1999. It considered issues of the A.C.E. design that
had not yet been completely worked out by the Census Bureau staff. Topics discussed included
methodsandissuesfordeterminingpost-strataforestimation,obtainingthefinalsampleofblock
clustersfromalargerinitialsample,andimputingvaluesformissingresponsesoncharacteristics
needed todefine post-strata.
The second workshop was held February 2–3, 2000. It covered the dual-systems estimation
process from beginning to end. The third workshop was held October 2, 2000. It laid out the
process the Census Bureauplanned to follow inorder toreach a decisionby March 1 on whether
to adjust thecensus counts for purposes of congressional redistricting.
This volume provides the edited transcript of the proceedings of the first workshop. (See
NationalResearchCouncil,2001band2001cforproceedingsofthesecondandthirdworkshops.)
The substance of the participants’ remarks has not been altered. Some text has been added [in
brackets] to spell out terms, clarify who is speaking, and make sentences complete. The only
material deleted consists of introductions of speakers. A list of invited participants and their
affiliations(at the timeof the workshop) is provided at the end of the document.
Papers prepared by Census Bureau staff were distributed to participants before the meeting.
They are often mentioned in the discussion, and appropriate citations have been added in the
text to refer the reader to the relevant bibliographicentry in the references. All of the documents
are availableon the Census Bureau’s web site: http://www.census.gov.
For explanations of terms and discussion of the design of the A.C.E. as it was implemented
in 2000, please consult the interim report of the panel, The 2000 Census: Interim Assessment
(NationalResearch Council, 2001a).
