About this ranking

US dollars, for the United States, its states and counties, and for every country and the World from the World Bank. For Spain and the EU in euros use gdp. Exchange rate swings move dollar values even when output does not.

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.
