If you add up the totals in these charts, 75% of minimum wage earners are adults. Let that sink in for a minute. 70% have at least a high school degree, and some have had at least a year or two of college. Take a look at the size of the big blue slice in the first pie chart — that represents adult women who are working for minimum wage, almost half of the total. This is why raising the minimum wage would make a huge difference for tons of families, especially those in which women are the primary breadwinners or single moms.
