- The Bureau of Labor Statistics provides the following data about U.S. workers ages 16 and older who were paid hourly rates in 2021. The table shows, overall and separately for men and women, the number of workers (in thousands, so that the upper left value of 76,125 represents over 76 million individuals) who were paid hourly that year and the number who earned the federal minimum wage or less.
