Establishment Selection Probabilities And Number Of Occupational Selections To Reduce
Variances In BLS Compensation Surveys," Proceedings of the Section on Survey Research

The National Compensation Survey (NCS) is the new BLS survey for measuring employee
wages by skill level. NCS uses a rotating panel design, with three stages of selection
used in selecting each panel: geographic area PSUs; establishments selected from industry
strata; and occupations selected separately from each sample establishment. The
establishments are selected with probability proportional to size (pps), with total
employment the measure of size. For each selected establishment the number of sampled
occupations are a function of employment size. This paper investigates two aspects of this
sample design. First, whether some other probability selection scheme for sampling
establishments yields lower variances than direct pps. Second, if there exists an
allocation by size class for the number of occupational selections that yields lower
variances than the current allocation.
