http://www.unionstats.comThe Union Membership and Coverage Database, available at [see blink below - NC*] 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 (Trinity University) and David Macpherson (Florida State University), is updated annually.
