Highlights

The number of congressional representatives a state receives, as well as district boundaries, are determined by a decennial census. A number of communities, contending that the 1980 census has missed large numbers of persons and that this undercounting will result in their citizens being shortchanged in political representations and federal fund distributions, have taken legal action to have the census count adjusted for the undercount. The Census Bureau dropped a postenumeration survey for estimating 1980 census errors at subnational levels, so that preliminary estimates would be available sooner. GAO reported on the Census Bureau's ability to develop accurate undercount estimates for subnational levels and the effect of dropping a planned post-census survey on the prospects for developing accurate undercount estimates.

Recommendations

Matter for Congressional Consideration

Matter Status Comments
Congress should enact legislation requiring that the Secretary of Commerce submit a report to the appropriate congressional committees having jurisdiction over the census, 18 months prior to each census, on whether and how he intends to prepare credible estimates of over/undercount at subnational levels, including characteristics for the undercounted persons. The report should include the cost and time needed to make these estimates and an independent assessment of the Bureau's proposed methods.
