For the past half-century, crime has been measured using data that increasingly extends beyond the criminal justice system alone. This article demonstrates how French public health surveys contribute to our understanding of young people’s relationship to violence. Some of these surveys provide information on the proportion of young people among perpetrators of assaults, but more importantly, they expand the scope to include forms of violence that traditional victimization surveys do not capture when estimating the overexposure of those under 25. The article analyzes the reasons for this and relates them to the specific characteristics of physical violence in this age group. [author’s abstract]
