Rankings

Definition

Union members as a percent of employed wage and salary workers, annual average, from the Current Population Survey of the U.S. Census Bureau and the U.S. Bureau of Labor Statistics (series LUU0204899600 for the nation).

Union members are members of a labor union or an employee association similar to a union. Annual averages of the monthly Current Population Survey, a household survey, so the figures carry sampling error, which is larger for small states. Wage and salary workers exclude the incorporated and unincorporated self employed. State figures are by state of residence. The 2025 averages cover 11 months: October 2025 was not collected during the federal government shutdown. For workers covered by a union contract, members or not, use union_representation_rate.
