This is ignoring a lot of variables, the most obvious of which is that crime rates for people in economically disadvantaged positions are unsurprisingly higher.

I was going to explain some of the others when I realized that in the context of this thread — namely comparing Europe to China in terms of ethnic diversity — these misleading statistics smell like a call to return to a ‘monocultural’ Europe. My grandparents have had pretty bad experiences with Germany’s last attempt at that; I therefore want to stress how dangerous it can be to present statistics like these as ‘neutral’.
