This book presents the first major release of findings from the Fourth International Self-Report Delinquency Study (ISRD4), an ongoing, multi-national project examining young people's experiences with both victimization and offending. Covering 21 countries, this book reports responses from 58,000 young people aged 13 to 17, exploring their experiences with crime as victims, offenders, and offender-victims. The book provides in-depth analyses of cross-national crime patterns, the victim-offender overlap, the overlap in both online and offline domains, and the experiences of serious and repeat victims and offenders. It concludes with a thought-provoking discussion of the implications for theory as well as policy.

Key takeaways from the study include:

• Cultural differences significantly impact the willingness to disclose offending behavior.
• Online victimization is an increasing concern, especially among girls and younger adolescents
• Overlap between online and offline forms of crime, and between victimization and offending is present in all countries
• Hate crimes and parental violence are more common than typically recognized.

Authored by an international team, this book is essential for researchers in criminology, criminal justice, sociology, public policy, youth studies, and psychology.
