The German government expects a total influx of 3.6 million refugees by 2020, with an average of half a million people arriving each year, German media reported on Thursday, in a country that took in a record 1.1 million migrants last year.
The calculations are based on internal estimates by the Economy Ministry in coordination with other ministries, German newspaper Sueddeutsche Zeitung said.
In order to project economic development, the Economy Ministry created "an internal, purely technical estimate on migration in coordination with other government departments".
