From Tax Foundation, "The Real Value of $100 in Each State" by Alan Cole and Scott Drenkard:

***The states where $100 is worth the most are Mississippi ($115.21) Arkansas ($114.29) South Dakota ($114.16) Alabama ($114.03) and West Virginia ($113.12). In contrast, $100 is effectively worth the least in the District of Columbia ($84.96) Hawaii ($86.06) New York ($86.73) New Jersey ($87.34) and California ($89.05.)

Regional price differences are strikingly large; real purchasing power is 36 percent greater in Mississippi than it is in the District of Columbia. In other words: by this measure, if you have $50,000 in after tax income in Mississippi, you would have to have after-tax earnings of $68,000 in the District of Columbia just to afford the same overall standard of living.
