The LEHD Infrastructure Files and The Creation of The Quarterly Workforce Indicators

Show Summary Details

Preview

This chapter reports a detailed documentation of the Longitudinal Employer-Households Dynamics Program (LEHD) data sources and the methods used to construct the Quarterly Workforce Indicators (QWI). It provides a valuable reference source for users of the QWI and the LEHD. The procedures implemented in the LEHD Infrastructure Files to detect, edit, and manage entity identifiers are addressed. The wage record editing process takes place in a secure computing area distinct from the rest of the LEHD processing. The edits and imputations associated with missing job-level data are explained. The three time series reveal considerable seasonality, but job creations and recalls are considerably more variable. The Census Bureau maintains lists of establishments to develop the frames for economic censuses and surveys. Finally, some of the ongoing efforts to enhance the LEHD Infrastructure Files are discussed.
