Where they live: censuses and official statistics
Each figure comes from the country's official census or official statistical survey (in the USA: the American Community Survey). Countries define belonging differently (nationality, citizenship, mother tongue, ancestry); the type is given on each row. The USA, Canada and Australia record ancestry, and people may report more than one. Many countries (France and Germany, for example) do not record ethnicity, so they are absent here.
