In its 2021 report on the phenomenon, the Swedish National Council for Crime Prevention did not analyse the reasons for the trend that occurred in Sweden.
[6] According to a report published by academic researchers in 2017, shooting incidents with fatal outcomes are about 4 to 5 times as common in Sweden compared to neighbouring countries such as Germany and Norway when taking population size into account.
[11] A 2018 systematic review of 25 studies on firearm violence in Sweden by criminologist and physician Ardavan Khoshnood, concluded "that even though knives/sharp weapons continue to be the most common MO in a violent crime in Sweden, firearm-related violence is significantly increasing in the country and foremost when discussing gang-related crimes.
"[12] According to researcher Amir Rostami at Stockholm University, police statistics for January–November 2018 showed that the number of shootings was at a continued high rate at 274, where up until the end of November 42 people had been shot and killed and 129 wounded compared to 43 in 2017.
About half the shooting resulting in killings took place in so-called vulnerable areas and represented an increase on the preceding year.
[2][15] According to researcher Amir Rostami in 2021, those responsible for the gun violence are predominantly young men and often second generation immigrants.
