This study investigates the direction and rate of change in self-reported crime over time, based on immigrant status and region of origin. The study is based on eight nationally representive school surveys conducted by the National Council for Crime Prevention between 1999 and 2017, with a sample of 50,657 adolescents. Results in this study showed a decreasing trend in self-reported offending among both first and second generation immigrant youth, and also among immigrant youths from different regions of origin. The results also show that offending has declined at a faster rate among first generation immigrants by comparison with native Swedes.
