About this ranking

Total income received by the residents of a place from work, own businesses, property and government benefits, before income taxes, in millions of current US dollars. United States: Bureau of Economic Analysis regional accounts, table SAINC1 line 1 for the nation and states and CAINC1 line 1 for counties.

Counted where people live, not where they work. The national figure is the total of the states, which differs slightly from personal income in the national accounts. Divided by BEA population it gives per_capita_personal_income.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
