International Self-Report Delinquency Study (ISRD) is an international collaborative study, which repeatedly (ISRD1, ISRD2, ISRD3, and now ISRD4) collects data on juvenile delinquency and victimization from comparable (but not identical) samples. Finland has been part of ISRD-projects since the first study sweep and studies have been carried out in Helsinki and Turku. Thus, the studies have provided unique information about young people’s safety and juvenile delinquency in Helsinki and Turku since the 1990s. ISRD uses a standardized self-report survey. Self-report surveys are used in criminological studies because only a limited amount of crime is reported to the police.

In this blog, we present the ISRD4 project, the fourth sweep of ISRD studies. The sweep-specific focus in ISRD4 is online offending and victimization, perceptions of violence, and minority groups and identity. Additionally, the youth street gang involvement module will be collected in Nordic countries. The Street Gang Involvement Among Nordic Youth: A Comparative Study On Prevalence and Risk Factors in Nordic Countries and Cybercriminal Careers: Comparative and Longitudinal Perspectives on Youth Cybercrime Offending studies will be presented in this blog, as they are based on ISRD4 data.
