About this ranking

Personal income of the residents of a place divided by its resident population at mid-year, in current US dollars.

More on how it is measured
  • Personal income is income from work, own businesses, property and government benefits, before income taxes.
  • United States: Bureau of Economic Analysis regional accounts, tables SAINC1 for the nation and states and CAINC1 for counties.

An average, not a median: high incomes pull it up. It includes employer contributions to pensions and health insurance and government benefits, so it is higher than wages or household cash income. For the typical household use median_household_income. Not the same as gdp_per_capita_usd.

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.
