Abstract:

Like most establishment surveys the Public Employment Survey data are highly skewed. Our goal was to reduce the number of small units included in the sample since they collectively account for a small percentage of the total and account for a disproportionate number of sample units. A first stage sample was selected via a probability proportional to size method within each state by type of government (city, county, township, special district, school district) using the sample sizes from the previous sample design. In the second stage, smallness was determined using the Cumulative Square Root of the Frequency method within selected states by type of government. After smallness was determined, a subsample of the stratum containing the small units was then taken to reduce the size while maintaining comparability with the previous sample.
