The latest minimum wage increase is now in effect in Washington, D.C. and Maryland.
As of Wednesday, the minimum wage in the nation's capital is $10.50 an hour. That's higher than in any state, although a handful of cities have approved minimum wages higher than the District's.
The D.C. Council approved the minimum-wage increase in late 2013, and then-mayor Vincent Gray signed it the following year. The wage increased to $9.50 an hour last July. Next July, it will increase by one more dollar to $11.50.
Mayor Muriel Bowser will discuss the increase at a news conference on Wednesday.
In Maryland, minimum wage increased by a quarter to $8.25.
The increase is one of several approved by the Maryland General Assembly last year, when then-Gov. Martin O'Malley made the increase a priority of his last legislative session as governor.
The first increase took effect in January, when the wage went from $7.25 to $8.
It is set to go up again to $8.75 in 2016 and $9.25 in 2017. It is scheduled to reach $10.10 in 2018.
