Many U.S. workers are ringing in the new year with a raise as new minimum wage increases take effect in states and localities across the country on Thursday.

More than 8.3 million workers are expected to benefit from minimum wage hikes in 19 states, which will collectively add an estimated $5 billion in earnings nationwide, according to a December report by the Economic Policy Institute.

On top of changes to state minimum wages, many cities and municipalities with local wage standards increased their minimum wages Thursday as well. For example, Seattle’s minimum wage rose to $21.30 an hour, and the minimum wage in Minneapolis is now $16.37 an hour.

Minimum wage workers in Hawaii will see the largest jump in their hourly pay. The state’s minimum wage rose by $2 per hour, from $14 to $16. Other states with minimum wage increases include Arizona, California, Michigan, New Jersey and New York.

The federal minimum wage remains at $7.25 an hour, where it has stood since 2009. Minimum wage levels vary widely depending on where workers live, with state and local laws often setting significantly higher standards.
