This study describes rates of violence victimization, perpetration, and witnessing in 6th-11th grade for a multisite sample (N = 3,466) of predominantly Black and Hispanic middle- and high-school students from urban areas with high rates of crime and economic disadvantage. Students completed surveys in middle and high school assessing teen dating violence, stalking, sexual violence and harassment, bullying, cyberbullying, and physical violence perpetration and victimization, as well as witnessing violence. The highest prevalence rates are observed most often in 8th or 9th grade. Youth reported high rates of witnessing serious assault and severe community violence throughout adolescence. These findings suggest that efforts to prevent violence among youth living in under-resourced communities need to start early and address community-level socioeconomic disparities.
