About 4.3 million American workers were affected by an increase in the minimum wage
across 19 states this week. 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.
