As promised here is the adjusted data from last night. Average household median income 2011-2013 per US Census Bureau, adjusted by 2012 Regional Price Parity by State(Commerce Dept, Bureau of Economic Analysis):
Top 5 states(in order highest income to lowest) New Hampshire, Virginia, Maryland, Minnesota, North Dakota.
Bottom 5(lowest to highest) Louisiana, New York, New Mexico, Mississippi, Arkansas.
Ave income(household) RTW $53120, non-RTW $54612.
The NH income data is skewed. Pretty much the southern half of NH is MA transplants but still working in MA. They report in NH but it's earned in MA.
