In the United States as a whole, the average income per capita (per person in the workforce) is $28,555.
When looking at the data for each state, it appears that New England has more people with higher incomes and the Southern states have the lowest. One must keep in mind, however, that the cost of living rises with the income of the area.
And one may be willing to give up some of that income for more ideal weather.
