I call doener kebab on that. Almost 10% are from Turkey. Depends on what you mean by almost.

If you count all from Turkish descent in Berlin, then that would be 6%. Most are 'white'.

It is less than 10% in Berlin and most of them are second or third generation descendants of immigrants and most definitely white Germans "mit Migrationshintergrund".
