(CNN) - Hundreds of thousands of minimum wage workers in 10 states will see a pay boost in the New Year.
Rhode Island, Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, Vermont and Washington will increase their minimum wage.
According to the non-profit advocacy group the National Employment Law Project, Rhode Island workers will see the biggest paycheck increases - an average of $510 a year for the average worker.
It comes after the state raised its minimum wage to $7.75.
The group says workers in nine other states, including Colorado, Florida and Ohio, will see the minimum wage will jump between 10 and 15 cents an hour.
All in all, an estimated 855,000 workers will be affected by the changes.
States must pay at least the same as the federal minimum wage, which has been set at $7.25 an hour since 2009.
In 2013, 19 states and the District of Columbia will have rates above the federal level.
