Abstract: A key aspect of the current integration of the BLS compensation surveys will
be to select future establishment sample for the Employment Cost Index (ECI) survey as a
subsample of the larger National Compensation Survey (NCS). Initially the transformation
of the ECI to a subsample of the NCS will take place by initiating five subsamples of the
current NCS sample over three years. This paper details our plans for the subsampling,
which involves several interesting issues. For example, the NCS sample is actually two
independent samples with some establishments selected twice, but the subsampling method
insures that no establishment will be selected more than once in ECI. Also, the
subsampling probabilities are determined with the goal that all establishments in an
industry stratum in the universe with the same frame employment have the same overall
chance of being in the ECI sample. Finally, we discuss the additional sampling
complexities arising from the fact that the current NCS sample consists only of
establishments with frame employment of at least 50, while the ECI has no minimum
employment restrictions, necessitating supplemental ECI samples of the smaller
establishments.
