About 4.3 million American workers were affected by a recent increase in the minimum wage across 19 states. In total, 29 U.S. states (and the District of Columbia) have now set a minimum wage level higher than the $7.25 an hour federal standard. Local districts aside, D.C. has the highest minimum wage in the U.S. at $11.50 with Massachusetts and Washington following with $11 each.
Arizona's low wage workers saw the largest leap in their minimum wage which went up by $1.95 to $10.00 in total. Many cities have higher higher local minimum wages. San Francisco and Seattle are notable examples and both will see their minimum wage hit $15 by 2018 and 2021 respectively.
