CNN - The minimum wage is set to rise in 21 states, at least 22 cities, four counties and one region. The majority of those increases will take place on Jan. 1, but in Maryland, Oregon and Washington, D.C., they go into effect in July. Meanwhile, the state of New York will be bumping up minimum pay on New Year's Eve of this year.
The biggest minimum wage raises, percentage wise, will be in Arizona (up 24% to $10), Maine (up 20% to $9) and three Silicon Valley cities (up 20% to $12).
In the absence of action from Congress in terms of raising the federal minimum wage, which has remained at $7.25 since 2009, states and localities have taken matters into their own hands.
