State minimum wages will exceed the federal minimum wage of $7.25 an hour in 21 states beginning on January 1. 

Connecticut, New York, New Jersey and Rhode Island legislatures voted to raise the minimum hourly wage by as much as $1, to $8 to $8.70, by Wednesday. In California, a $1 increase to $9 is scheduled July 1.

The trend reflects growing concerns about the disproportionate spread of low-wage jobs in the U.S. economy. 

Here are the 13 states increasing minimum wage on January 1:

Arizona: $7.90

Colorado: $8.00

Connecticut: $8.70

Florida: $7.93
