In 2013, the union membership rate - the percent of wage and salary workers who were members of unions - was 11.3 percent, the same as in 2012, the U.S. Bureau of Labor Statistics reported today. The number of wage and salary workers belonging to unions, at 14.5 million, was little different from 2012. In 1983, the first year for which comparable union data are available, the union membership rate was 20.1 percent, and there were 17.7 million union workers.
Public-sector workers had a union membership rate (35.3 percent) more than five times higher than that of private-sector workers (6.7 percent).
