The share of people with a migrant background in Germany rose to 21.2 million last year, the Federal Statistical Office said in a report on Tuesday. They represent roughly 26% of Germany's population, EDNews.net reports citing Deutsche Welle.

The figure represented a 2.1% increase from the previous year, but it was the slowest rise in people with a migration background since 2011.

In Germany, a person is considered to have a ''migration background'' (Migrationshintergrund) if they, or at least one of their parents, were born without German citizenship. Being born in Germany is not an automatic qualification for citizenship as in some countries, although in the majority of cases, eight years residence will suffice. 

Of the 21.2 million people with a migrant background, just over half were born as German citizens, meaning at least one of their parents had become or was a German citizen.

Some 65% of all people with a migrant background came from another European country. Of these, roughly, 7.5 million (35%) people with migrant background came from a fellow EU member state.

Asians accounted for 4.6 million people or 22% of all inhabitants with a migrant background. Some 3.2 million (15%) came from the Middle East and just under 1 million people (5%) had roots in Africa. A little over half a million people (3%) came from North, Central and South America and Australia.

The largest single group, forming some 13% of people with a migrant background, originated from Turkey. Those from Poland and Russia followed respectively.

Location varied significantly, with a higher share of people with migrant backgrounds clustered in the west. The northwestern city-state of Bremen has the highest figures, with 36.5% of its total population having a migrant background. In contrast, the eastern state of Thuringia had only 7.8%.
