The percentage of workers belonging to a union (or total labor union "density") varies by country. In 2019 it was 10.3% in the United States, compared to 20.1% in 1983. There were 14.6 million members in the U.S., down from 17.7 million in 1983. Union membership in the private sector has fallen to 6.2%, one fifth that of public sector workers, at 33.6%. Over half of all union members in the U.S. lived in just seven states (California, New York, Illinois, Pennsylvania, New Jersey, Ohio, and Washington), though these states accounted for only about one-third of the workforce. From a global perspective, in 2016 the US had the fifth lowest trade union density of the 36 OECD member nations.
