SNAP usage, state-by-state

See this map and accompanying story by Maria Goody on NPR's The SALT.  The map, by Stateline,  shows the percentage of residents in each state who receive SNAP--also known as food stamps.  Goody observes:

While Republicans have led the call to slash the SNAP program in the House, many of the states whose residents are most reliant on food stamps are reliably Republican and located in the GOP's Southern heartland. About 20 percent of the population in Tennessee, Georgia, Louisiana, Mississippi, Kentucky, and South Carolina, for instance, receive benefits from the federal food assistance program.

Other states with very high food stamp usage are Oregon and New Mexico at 21% each.
