About this ranking
Unemployed people as a percentage of the labour force, using the survey definition of unemployment: without work, available and looking for work. Spain: EPA, aged 16 and over. EU: Labour Force Survey, aged 15 to 74. United States: civilian labour force aged 16 and over, from the Current Population Survey for the nation and from BLS Local Area Unemployment Statistics models, consistent with that survey, for states and counties. Other countries and the World: ILO modelled estimates published by the World Bank, aged 15 and over.
Survey-based. Available for Spain, regions, provinces, EU countries, US states and US counties, not Spanish municipalities. For municipalities use registered_unemployment_rate. US national and state rates are seasonally adjusted; county rates are not. Countries without a national or Eurostat series get the annual ILO modelled estimate, a model output rather than a survey result.
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.
