Notes: Data allowing for a disaggregation of the public sector into federal government and state and local government became available in 1989. The sharp increase in the public-sector union membership rate between 1961 and 1962 can be attributed to the passage of Executive Order 10988, which gave federal employees the right to collectively bargain (see “50th Anniversary: Executive Order 10988,” Federal Labor Relations Authority, 2012).
