The National Conference of State Legislatures has a web page devoted to minimum wage for each state, as of 2015. This web page also allows users to search for minimum wage legislation particular to their individual states.
The last year that the U.S. Congress amended the Fair Labor Standards Act (FLSA) was 2007. They passed a three-step increase that raised the federal minimum wage to $7.25, and it has remained there since 2009. The FLSA establishes the standards for hourly minimum wages, record-keeping, overtime pay and child labor. There were more than 75 million workers paid on an hourly basis in 2012, and 3.6 percent of those workers were minimum wage workers.
As of January 2015, there are 29 states that have minimum wages above the federal minimum wage. Alaska, Arkansas, Nebraska and South Dakota approved minimum wage increases in 2014 through ballot measures in the general election, while Illinois voters approved an advisory measure.
In 2014, legislatures in Delaware, Hawaii, Connecticut, Maryland, Michigan, Massachusetts, Rhode Island, Minnesota, Vermont, West Virginia and D.C. initiated minimum wage increases. Nine states had their minimum wages increase in 2015 due to indexed increases in those states: Arizona, Colorado, Florida, Missouri, Montana, New Jersey, Ohio, Oregon and Washington.
