Or that a lot of states have the federal minimum wage, but like 5% or even less people earn that.

Found the stat on BLS:

> In 2020, 73.3 million workers age 16 and older in the United States were paid at hourly rates, representing 55.5 percent of all wage and salary workers. Among those paid by the hour, 247,000 workers earned exactly the prevailing federal minimum wage of $7.25 per hour. About 865,000 workers had wages below the federal minimum. Together, these 1.1 million workers with wages at or below the federal minimum made up 1.5 percent of all hourly paid workers.

North Carolina data from 2015 only because I knew it was out there:

> Regional Commissioner Janet S. Rankin noted that the 122,000 workers earning the federal minimum wage or less made up 5.1 percent of all hourly paid workers in the state. Nationwide, those earning the federal minimum or less accounted for 3.3 percent of the hourly paid workforce. (See table 1. The North Carolina minimum wage is equal to the prevailing federal minimum wage.)
