This research looks at the traits of members of violent extremist organizations in Sweden, specifically examining Islamic, far-right, and far-left extremists. Demographic, socioeconomic, criminal, mental health, and familial characteristics are compared using data from the Swedish population and law enforcement. The results emphasize notable distinctions, such as lower rates of severe mental problems and more criminal participation among Swedish extremists, while also demonstrating parallels to worldwide patterns in age and sex. There is evidence of intergenerational transmission as violent Islamic extremists in Sweden are more likely to have extremist family members. The study highlights how crucial it is to take national circumstances into account while combating violent extremism.
