Note: Data refer to members of a labor union or an employee association similar to a union. Data refer to the sole or principal job of full- and part-time wage and salary workers. All self-employed workers are excluded, both those with incorporated businesses as well as those with unincorporated businesses.
In 2014, 30 states and the District of Columbia had union membership rates below the U.S. average of 11.1 percent. Nineteen states had rates above the U.S. average, and one state had a rate equal to the U.S. average. All states in the East South Central and West South Central divisions had union membership rates below the national average, and all states in the Middle Atlantic and Pacific divisions had rates above it. Union membership rates declined over the year in 27 states and the District of Columbia, rose in 18 states, and did not change in 5 states.
These data are from the Current Population Survey. To learn more, see "Union Members — 2014" (HTML) (PDF). The union membership rate is the percentage of wage and salary workers who are members of unions. The numbers exclude all self-employed workers.
