U.S. migrant origins less diverse than European Union's % of total internationalmigrants in the US/EU who are from each of their top four origin countries United States EU, Norway &Switzerland
But while the U.S and EU have large migrant populations from many parts of the world, the origins of U.S. migrants are less diverse. About a quarter (26%) of all immigrants in the U.S. come from just one country – Mexico. By contrast, Turkey was the top origin country for EU migrants (excluding internal migrants) in 2015 – but its 8% share does not nearly rival Mexico’s in the U.S.
