Numbers of minimum-wage workers are much more prevalent in some states than others. The most recent 2017 federal estimates suggest employees earning the federal minimum wage or less are most prevalent in Kentucky (4.4 percent), Mississippi (4.1 percent) and Tennessee (4.1 percent). These workers were least common in California, where they accounted for just 0.5 percent of the workforce.
Several factors explain variations across states. Most notably, more than half of states have enacted their own minimum wage laws, some well above the national rate. Differences in cost of living and concentrations of various low-paying industries also influence how many workers make at or below the federal minimum wage.
The following map shows each state's two-year average share of minimum wage workers as a percentage of all hourly workers for 2016-2017.
