About this chart
The share of US wage and salary workers in a union fell from 20.1% in 1983 to 10.0% in 2025, according to the Bureau of Labor Statistics. The rate dropped below 15% in 1995 and below 12% in 2010, and 9.9% in 2024 was the lowest in the series. In 1983, 17.7 million workers were union members, compared with 14.7 million in 2025. The rate rose to 10.8% in 2020 before settling back.
The 2025 rate was 32.9% for public-sector workers and 5.9% for private-sector workers. The 2025 annual estimate uses 11 months of data because October 2025 survey data was not collected during the federal government shutdown, so it is not strictly comparable. The series covers employed wage and salary workers aged 16 and over in the Current Population Survey and starts in 1983, the first year with comparable data.
