The Current Population Survey (CPS), a nationwide household survey
conducted by the Bureau of the Census for the Bureau of Labor Statistics,
provides official labor force estimates for the working-age noninstitutional
population. Variances for the labor force estimators are based on a modified
half sample replication method. Since the variances are based on a sample,
the variance estimates have a considerable amount of error. One method to
remove some of the sampling error in the variances is to group similar labor
force items and fit a generalized variance function to the variance
estimates. This paper evaluates the current variance estimation procedure
and suggests another procedure for generalizing variances for national labor
force statistics.
