Thanks to legislative efforts, ballot measures and adjustments for inflation, workers in 20 states will see an increase in their minimum wage in 2019.

These minimum wage increases, which range from a $0.05 inflation adjustment to a $2 per hour increase, will impact 5.2 million workers and, for those who work year-round, it will raise their annual pay between $90 and $1,300, according to a recent Economic Policy Institute report . On Jan. 1, 2019, 24 cities and counties will also raise their minimum wages.

Though the federal minimum wage has remained at $7.25 an hour since 2009, there has been a growing movement across the nation to raise this number at both the state and local levels.

In 29 states, the minimum wage now surpasses the federal level, and a handful of state have pledged to raise their minimum wage to $15 an hour over the next few years.

Out of the 20 states increasing their minimum wage in 2019, six of them -- California, Delaware, Massachusetts, Michigan, New York and Rhode Island -- are increasing wages thanks to laws set by their state legislatures, according to the Economic Policy Institute.

In Arizona, Arkansas, Colorado, Maine, Missouri and Washington, voters approved a minimum wage increase through ballot measures. And in eight other states -- New Jersey, Ohio, South Dakota, Vermont, Alaska, Florida, Minnesota and Montana -- the minimum wage was raised as a result of automatic adjustments for inflation.

Nevada could join these 20 states in increasing its minimum wage, depending on the outcome of review by the state's labor commissioner as to whether the minimum wage is properly adjusted for inflation.
