Eight states had union membership rates below 5.0 percent in 2018. After the Carolinas, the next lowest rates were in Utah (4.1 percent) and Texas and Virginia (4.3 percent each).
The largest numbers of union members lived in California (2.4 million) and New York (1.9 million). Over half of the 14.7 million union members in the United States lived in just seven states (California, 2.4 million; New York, 1.9 million; Illinois, 0.8 million; Pennsylvania, 0.7 million; and Michigan, Ohio, and Washington, 0.6 million each). These states accounted for only about one-third of wage and salary employment nationally.
These data are from the Current Population Survey. To learn more, see "Union Members — 2018." The union membership rate is the percent of wage and salary workers who were members of unions. The numbers exclude all self-employed workers.
