Detention in Delinquency Cases, 1987–1996 (FS 99115) August 1999 Fact Sheet 2 page(s) MacKenzie, L. R. Provides information related to the courts' use of detention in delinquency cases from 1987 to 1996. In 1987, 1.2 million delinquency cases were disposed in juvenile courts. By 1996, this number had risen 49%, to almost 1.8 million. This increase in the volume of juveniles in the justice system resulted in a 38% increase in the number of delinquency cases that involved the use of detention. The number of juvenile delinquency cases detained in 1996 was 89,000 more than in 1987. This has resulted in increased demand for juvenile detention bed space across the country. PDF Text
