 Union Membership, Coverage, and Earnings from the CPS 

 Union data 
compilations from the 2025 CPS completed January 23, 2026. 

 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), 
 David Macpherson 
 (Department 
of Economics, Trinity University), and William Even 
 (Department of Economics, Miami  University),was created in 2002 and is updated annually.

   Note: 
CPS sample sizes are very small for some cells.  Use 
such estimates cautiously.
