A slew of recent legislation at the state and municipal levels has pushed the minimum wage in some places far above the $7.25 standard set by the federal government.

More than half of all U.S. states require employers pay their staff hourly wages greater than $7.25 and in some cities, like San Francisco and New York, the minimum wage hit $15. That's more than double the federal rate, which has not been increased since 2009.
