BLS: Union Membership Declined in 2018
Over half of labor union members live in just seven states.
The union membership rate—the percent of wage and salary workers who were members of unions—was 10.5 percent in 2018, down by 0.2 percentage point from 2017, the U.S. Bureau of Labor Statistics reports.
The union membership rate of public-sector workers (33.9 percent) continued to be more than five times higher than that of private-sector workers (6.4 percent).
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 U.S. 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), though these states accounted for only about one-third of wage and salary employment nationally.
