This is from 2017, which is three years younger than what you are citing. Even if you fast forward to 2019, these numbers haven't changed much.

In 2017, 80.4 million workers age 16 and older in the United States were paid at hourly rates, representing 58.3 percent of all wage and salary workers. Among those paid by the hour, 542,000 workers earned exactly the prevailing federal minimum wage of $7.25 per hour. About 1.3 million had wages below the federal minimum. Together, these 1.8 million workers with wages at or below the federal minimum made up 2.3 percent of all hourly paid workers.
The percentage of hourly paid workers earning the prevailing federal minimum wage or less declined from 2.7 percent in 2016 to 2.3 percent in 2017. This remains well below the percentage of 13.4 recorded in 1979, when data were first collected on a regular basis. (See table 10.)
This report presents highlights and statistical tables describing workers who earned at or below the federal minimum wage in 2017. The data are obtained from the Current Population Survey (CPS), a national monthly survey of approximately 60,000 households conducted by the U.S. Census Bureau for the U.S. Bureau of Labor Statistics (BLS). Information on earnings is collected from one-fourth of the CPS sample each month.
