ABSTRACT
In the Pittsburgh Youth Study, information about offending was obtained from boys, mothers, and teachers, initially every 6 months and then every 12 months. This information was analyzed between ages 7 and 14 for the 500 boys in the youngest sample and between ages 13 and 20 for the 500 boys in the oldest sample. The information from the two samples was combined to investigate offending from age 7 to age 20. This paper reports on: (a) ages of onset of serious and violent offending; (b) prevalence of serious and violent offending at different ages; (c) frequency of serious and violent offending at different ages; and (d) the persistence of serious and violent offending.
