Abstract:

Recently, the Census Bureau revised the estimates of coverage error in Census 2000 from the Accuracy and Coverage Evaluation Survey (ACE). As was done with the original ACE estimates in 2001, the Census Bureau conducted a thorough assessment of the revised estimates. One of the methods used in the evaluation was a loss function analysis. Using estimates of sampling and nonsampling error components, we formed bias and variance components for the revised estimates. Then we used the results of a total error model in a loss function analysis to assess the relative accuracy of the census and the coverage error estimates. The paper discusses the total error model, the estimation of its error components, and the results of the loss function analysis.
