On Jan. 1, nearly a million workers in 10 states will see the value of their paychecks preserved against inflation. Workers in Arizona, Colorado, Florida, Missouri, Montana, Ohio, Oregon, Vermont, and Washington are protected each year by automatic indexing of their state’s minimum wage. Indexing links the value of the state minimum wage to inflation so that as prices go up, so does the amount that minimum-wage workers must be paid. Low-wage workers in Rhode Island will also see a small boost to their incomes in 2013 thanks to a one-time increase in their state’s minimum wage that was enacted this past June.
