2000 Census: Coverage Evaluation Matching Implemented as Planned, but Census Bureau Should Evaluate Lessons Learned.

摘要

To assess the quality of the population data collected in the 2000 Census, the U.S. Census Bureau conducted the Accuracy and Coverage Evaluation (A.C.E.) survey, a sample of persons designed to estimate the number of people missed, counted more than once, or otherwise improperly counted in the census. A critical component of the A.C.E. survey was the person matching operation, in which the bureau matched the persons counted in the A.C.E. survey to the persons counted in the census. This report, prepared at the request of the chairman and ranking minority member of the former House Subcommittee on the Census, reviews the person matching operation of A.C.E. We agreed to describe (1) the process and criteria involved in making an A.C.E. and census person match, (2) the quality assurance procedures used in the key person matching phases and the available results of those procedures, and (3) any deviations in the matching operation from what was planned. This report is the latest of several we have issued on lessons learned from the 2000 Census that can help inform the bureau's planning efforts for the 2010 Census.
