In general, the Turk-German population are more moderate, and inclined to accept partying, booze, and weed. If anyone wanted to attach any negative to them....it’s that they do have some crime ‘clans’ existing.
The statistics are published by the national statistics organization, and not favored by any political party. So they tend to be accurate and not ‘stewed’. When you see statistics by a private foundation...then you have the right to suggest the data is suspicious.
