The union membership rate in the U.S. in 2018 dropped 0.2 percent from 2017 after remaining unchanged from 2016 to 2017, according to data from the U.S. Bureau of Labor Statistics. The overall percent of wage and salary workers who were members of a union was 10.5 percent last year with 14.7 million union workers. The total number of union members has dropped nearly in half since 1983, the first year for which comparable union data is available, when the membership rate was 20.1 percent with 17.7 million union workers.
Membership in unions related to construction also decreased in 2018, with 1,048,000 total union members, or 12.8 percent of the overall wage and salary construction workers. That’s down from 14 percent in 2017 when there were 1,102,000 members of construction unions. However, membership in construction-related unions remains higher than the national rate. The rate of construction workers represented by unions fell from 14.7 percent in 2017 to 13.8 percent in 2018.
