In 2005, 12.5 percent of wage and salary workers were union members, unchanged from 2004. The union membership rate has declined from a high of 20.1 percent in 1983, the first year for which comparable union data are available.
In 2005, the union membership rate was higher for men (13.5 percent) than for women (11.3 percent). The gap between their rates has narrowed considerably since 1983, when the rate for men was 10 percentage points higher than the rate for women. This narrowing occurred because the union membership rate for men declined more rapidly than the rate for women over the period.
Blacks were more likely to be union members (15.1 percent) than were whites (12.2 percent), Asians (11.2 percent), or Hispanics (10.4 percent).
