Employed wage and salary workers, union members and workers represented by unions (members plus workers covered by a union contract) in every state, DC and the nation, from the Bureau of Labor Statistics' annual Union Members release (Current Population Survey): numbers in thousands as BLS prints them, each as a percent of employed workers, for the latest year and the year before, with the change in the members' percent. The 2025 annual figures average the 11 months BLS published (January to September, November and December). 52 records (status: P 52).
