"Maybe it’s because Somalis in the west are predominantly impoverished working class refugees who therefore live in low income high crime neighbourhoods (hood/ghetto/council estate) and attend those schools? Maybe that might play a role? Maybe half the diaspora being <22 might help?"
The area you're raised in absolutely matters. Literally, a large majority of the guys I went to high school with in my neighborhood didn't attend college after we graduated. Only the Mexicans in my neighborhood joined the trades immediately after graduating. For everyone else, only a few joined the military, and the rest just started working random jobs or they started scamming/drug dealing. Only me and a few other Africans in my neighborhood went straight to college.
"Maybe it’s because the diaspora is disproportionately young and we all know young men in particular are crime factories."
upbringing plays a big role in how young men turn out. A majority of the men graduating from colleges with great degrees had educated parents who raised them to take school seriously. A majority of the young men who joined the trades right after high school had family members who worked in the trades. Even in the military, many young soldiers have a family member who also served.
A lot of our criminals had parents who didn't raise them to survive here in the West. Many of these parents had no idea how to do this.
I've said it on here before, but I truly believe some of our young men stood no chance here in the West. I'd say the same thing for some Somali women as well.
