Research attempted to determine whether the observed decrease in police diversion in Canada after the Young Offenders Act (1984) came into effect could have resulted from the addition of older young persons, with their presumably more serious crime, to the jurisdiction of the youth police system in most provinces and territories. The document discusses and presents data concerning: (1) youth crime and young offenders, 1992 and 1993; (2) age, gender and the amount of crime; (3) gender and the amount of crime; (4) age, gender and the seriousness of youth crime; (5) the onset and cessation of youth crime; (6) the likelihood of charges being laid; and (7) summary of research hypotheses.
