In January 2025, the Government commissioned the Swedish Defence Research Agency (FOI) to increase knowledge about how a criminal lifestyle is promoted on social media and in other digital milieus, and how this can influence young people's attitudes toward violence and crime (Ju2025/00157). For the purpose of this study, a national school survey and an interview study were conducted. The school survey was completed by just over 6,000 students in elementary and high school. The interview study included conversations with boys placed in the Swedish National Board of Institutional Care's special youth homes, staff at each home, as well as field assistants (field groups) and youth centre staff from across the country. The study shows that Swedish youth navigate a digital environment where exposure to violence and crime is common and difficult to avoid. The study indicates that online vulnerability is often rooted in the youth's social and local context. Furthermore, the study shows that young people who hold positive or accepting attitudes toward violence or crime share the following characteristics: they engage with violent content in digital environments to a greater extent than others, view status as important, hold gender-conservative values, and have less trust in society and its institutions. The study cannot establish whether there are causal relationships between these co-varying opinions, values, and experiences and digital content. The study finds that the effects of socioeconomic, local, and demographic factors are often greater than those connected to values or exposure to digital content.
