Union Membership and Coverage Database from the CPS
(Documentation)
The
Union Membership and Coverage Database, available at www.unionstats.com,
is an Internet data resource providing private and public sector labor union membership,
coverage, and density estimates compiled from the Current Population Survey
(CPS), a monthly household survey, using BLS methods. Economy-wide estimates are provided beginning
in 1973; estimates by state, detailed industry, and detailed occupation begin
in 1983; and estimates by metropolitan area begin in 1986. The Database, constructed
by Barry Hirsch (Georgia State University) and David Macpherson (Florida State
University), is updated annually.
Use of figures from the Database requires citation.
A
description of the Database is provided in the paper
