The page "German Language and Population" provides an overview of native German speakers and people of German origin combined with migration to and from Germany. Data on migration comes from the World Bank's extensive databases.
The data for German speakers and German citizens are taken from the respective Wikipedia articles (Germans
, German Language
). Since both articles access different data sources, the data for some countries are partly estimated. Basically: The more "rounded" the numbers, the more unclear the data situation!
