On Estimating Census Undercount in Small Areas
Cary T. Isaki, Linda K. Schultz, Gregg J. Diffendal, and Elizabeth T. Huang
Abstract:Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1990 decennial census.
Keywords:Census; undercount; adjustment; small area estimation; synthetic estimation; regression; artificial population; simulation.
