Union Membership and Coverage Database from the CPS
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 monthly household Current
Population Survey (CPS) 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 (Andrew Young School of Policy
Studies, Georgia State University) and David Macpherson (Department of
Economics, Trinity University), was created in 2002 and is updated
annually.
