Ten states raised their minimum wage at the start of 2013.
On Tuesday, Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, Rhode Island, Vermont and Washington raised wages between 10 and 35 cents.
The increase will put an extra $190 to $510 per year into the pocket of the average minimum-wage worker, according to Reuters.
African-Americans make up about 15.1 percent of the 73.9 million minimum wage earners in America.
A study by National Employment Law Project released last month reported that the wage increase for the ten states will affect pay for 995,000 American workers.
