This paper investigates the impact of parents' history of violent offending, their age at first birth, and the interaction of the two on their adolescent children's violent behavior. We employ intergenerational longitudinal data from the Rochester Youth Development Study to estimate parental trajectories of offending from their early adolescence through early adulthood. We show that the particular shape of the parents' propensity of offending over time can interact with their age at first birth to protect their children from delinquency. We investigate these relationships for children at 6 and 10 years of age. We find that for some groups delaying childrearing can insulate children from their parents' offending.
