Abstract
Larry Ernst, Christopher Guciardo, Chester Ponikowski, and Jason Tehonica (2002) "Sample Allocation and Selection for the National
Compensation Survey."
Recently, the first of five rotating replacement sample panels was
selected for the integrated National Compensation Survey (NCS) Program,
which includes the Employment Cost Index (ECI), Employee Benefits
Survey, and locality wage surveys. This paper explains, for these
surveys, how the sample of establishments was allocated to and selected
from industry strata and geographic PSUs, and discusses several
interesting issues. For these surveys, we describe how the universe of
establishments was divided into two groups: one consisting of larger
units that will be in the sample for all five sample panels, and the
other consisting of units to be selected independently for each panel.
Also, we describe how we forced the ECI sample to be a subsample of the
parent NCS sample, despite sampling requirements that would not seem to
guarantee this outcome. Finally, we describe how we selected the sample
from allocation cells that contain clusters rather than single PSUs, a
clustering that was necessitated by the fact that for some industry
strata the number of sample units allocated to a cluster is smaller than
the number of PSUs in the cluster. Several other allocation issues are
also discussed.
