There are some differences. Sweden, for various reasons, seems to cluster immigrants into fewer places with more of them all together. And the clustering creates service shortages for police, social services, jobs, etc. This makes for more kids that should be in school to not be in school, and also higher unemployment than there would be if they were more spread out. That heavy clustering also creates fewer opportunities to integrate with the locals, so the immigrant communities are more insular. All of that makes it easier for extremists to recruit, intimidate, organize, etc.
