Starting January 1, minimum wage workers in 13 states and four cities will see higher paychecks.

While most of the increases amount to less than 15 cents per hour, workers in places like New Jersey, Connecticut, New York and Rhode Island will see a bigger bump. Earlier this year, New Jersey residents voted to raise the state's minimum wage by $1 to $8.25 per hour. And lawmakers voted to hike the wage by between 25 cents and 75 cents per hour, to $8.70 in Connecticut and $8 in Rhode Island and New York. Residents in Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, Vermont and Washington will see a higher wage floor due to annual cost of living adjustments.

The Economic Policy Institute, a left-leaning think tank, used Census data to estimate that the increases will boost the incomes of 2.5 million low-wage American workers next year.
