Based mainly on personal experience and conditions prevailing in Malaysia, this discussion of juvenile delinquency explores (1) the extent of the problem; (2) some causative factors from a theoretical viewpoint; (3) criminal justice system provisions for dealing with the problem; and (4) preventive measures. In Malaysia, between 1960 and 1980 the number of juvenile offenders brougnt before the courts increased by nearly 40 percent. Nearly all offenders were male. Only 0.14 percent of all minors were delinquent. As in other countries, delinquency in Malaysia is largely an urban phenomenon brought about mainly by the process of national development and, more specifically, by the increasing pace of industrialization and urbanization. Poverty, in itself, is not a cause, but combined with other circumstances may induce delinquency. Other possible causes of delinquency are suggestd by cultural-transmission theory, psycho-biological perspectives, and family and community factors. When a juvenile has been found guilty of a crime, courts may order either institutional or community-based treatments, depending on the gravity of the offense and other factors. In treatment, community influence is great. Through carefully selected volunteers, the community can help juveniles grow out of their delinquency. The family, in various ways, can play a vital role in the prevention of delinquency. (RH)
