Actually, I think it's more complicated that that. I can't find the data but I remember a report that stated that Somali and Iraqi immigrants had 5 time higher conviction rate, and that more than 25% had been convicted for a crime, compared to ~5% of swedes.
I also remembered that immigrants from Sri Lanka -that have been a conflict zone for a very long time - had more or less half the conviction rate than Swedes, which is an interesting fact.
