About this ranking

Gross domestic product at current prices in US dollars divided by the resident population.

United States, states and counties: Invokely calculation, BEA current-dollar GDP divided by the BEA mid-year population of the same year and place; both inputs are shown with each value. GDP is counted where production happens and population where people live, so places with many commuters or capital-intensive industries, such as the District of Columbia or oil counties, show very high values. Not the same as per_capita_personal_income. For Spain and the EU use gdp_per_capita (EUR) or gdp_per_capita_pps. Other countries and the World: World Bank, converted at official annual average exchange rates (market rates, not purchasing power parity, so it understates living standards in lower-price countries). For euros use gdp_per_capita.

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.
