This article describes the juvenile crime trend and responses to juvenile delinquency in Hong Kong since the 1970s. It explores how changing conceptions of the causes of juvenile crime have influenced delinquency control policies. Although Hong Kong has a relatively low crime rate, the heavy emphasis on the use of custodial programs over community-based programs is obvious. Whereas the scope of delinquency literature is narrow and the legal professional’s opinion is rather conservative, new initiatives to further advance the juvenile justice system are difficult.
