Introduction. This study examines the age-specific risk factors associated with radicalization that could contribute to Swedish research and responsible investigative authorities. Specific knowledge of individual risk factors for radicalization is remarkably limited, especially compared to what we know about other forms of violence. Methods. A total of 1240 cases are included after a data cleaning of the PIRUS- dataset. An exploratory factor analysis examined youths (<21), adults (>22), and a no age-specific group. Results. The younger population tends to have more often been abused as a child, had some traumatic experience, and are currently part of a gang. In comparison, the older population tend to have alcohol or drug abuse problems and more unstructured time, have a radicalized friend and have actively searched for their radicalized group. The All-group shares a variety of variables with the age-specific groups. Conclusion. The results imply a need for specified risk factors according to age. The age-specific analysis provides a deepened understanding of age-specific risk factors that contribute to radicalization and make individuals susceptible to radicalized groups. Since different authorities are responsible for minors and adults and already work with a risk factor approach, the findings in this essay imply that the authorities should investigate their current policies and update them to age-specific risk factors if necessary.
