As the article in The Critic itself points out, it is hardly surprising that a group that is disproportionately made up of young, single men are more criminal than the general population, since young men are overwhelmingly more criminal than anyone else, and single men are likely plausibly worse. It’s not clear what this tells us about immigrants even from Syria or Afghanistan, let alone anywhere else, if we control for that. My guess for what it’s worth is that they will still have higher crime rates even if you control if they are Syrians (don’t know about Afghans, suspect more positive selection there), but you’d need to actually look.
