About this ranking

Total money income received in the past 12 months by people aged 15 and over, divided by the total population, including children, in US dollars adjusted to the last year of the period. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

Survey-reported money income before taxes. Lower than BEA per_capita_personal_income, which also counts employer contributions, imputed income and government transfers in kind.

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.
