Empirical evidence has been accumulating suggesting that victims and offenders share common risk factors
and are often one and the same. Guided by this extant literature, this study provides a longitudinal examination of the
relationship between physical aggression and violent victimization among a large sample of 2,671 urban minority youth
and young adults from Chicago. The results from a series of bivariate probit regression models, which allow the equations
for physical aggression and violent victimization to be estimated simultaneously, reveal strong evidence of a victimoffender
overlap. Additional results suggest that this victim-offender overlap cannot be merely explained away by a
commonality of risk factors and demographics alone. Study limitations and policy implications are also discussed.
