Union Membership and Coverage Files from the Current Population Surveys: Note

This note informs readers about the availability of disaggregated annual unionization data compiled from the Current Population Surveys (CPS). Union membership, membership density, and contract coverage density are calculated for employed civilian wage and salary workers from the monthly CPS for January 1983 through December 1991. Workers are classified by demographic and labor market characteristics, industry, occupation, state, metropolitan area, and state-by-industry. The union membership and coverage files described in the note are available from the authors, without charge, in machine-readable form.
