The most relevant figures would be homicide rate by perpetrator country of origin. Allegedly, 85% of shooting suspects are 1st or 2nd generation immigrants [0].

The most relevant figures would be homicide rate by perpetrator country of origin. Allegedly, 85% of shooting suspects are 1st or 2nd generation immigrants [0]. But reliable figures are hard to come by, partly because if scientists, even accidentally, find that, e.g., most rapes are committed by immigrants, they get prosecuted (eventually the charges were dropped, because they couldn't prove "bad intentions", negligence, or carelessness) [1,2,3,4]. The other reason is that, though Sweden used to collect data about criminal's ethnic background, they stopped I think in 2005 [5]. Though it seems they've resumed - in searching for sources for this post, I found https://emilkirkegaard.dk/en/2021/11/sweden-finally-publishes-new-immigrant-crime-rate-data-which-shows-no-surprises/ https://emilkirkegaard.dk/en/2021/11/sweden-finally-publishe...
