Comparing Sweden to Chicago seems a bit of a stretch. A number more directly comparable would be the US Non-Black homicide rate, which was 2.54 per 100,000 in 2015.
I think that's lower than the Sweden figure in the sibling comment.
[Edit: I had said that this rate was also lower than England. I was wrong on that one. ]
