About this ranking

Annual percentage change of GDP in chain-linked volumes, or at constant prices in the World Bank series.

Each value comes from one official source for that place: national statistics offices, Eurostat, for the United States the Bureau of Economic Analysis or, for other countries and the World, the World Bank. Annual values compare one calendar year with the previous one; quarterly values compare a quarter with the same quarter a year earlier. Past values can be revised. United States figures come from BEA tables SAGDP11 for the nation and states and CAGDP11 for counties. Growth in small counties can swing widely from year to year.

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.
