The United States incarcerates more of its youth than any other country in the world through the juvenile courts and the adult criminal justice system, which reflects the larger trends in incarceration practices in the United States. In 2010, approximately 70,800 juveniles were incarcerated in youth detention facilities alone. Approximately 500,000 youth are brought to detention centers in a given year. This data does not reflect juveniles tried as adults. Around 40% are incarcerated in privatized, for-profit facilities.
The system that is currently operational in the United States was created under the 1974 Juvenile Justice and Delinquency Prevention Act.
The Juvenile Justice and Delinquency Prevention Act called for a "deinstitutionalization" of juvenile delinquents. The act required that states holding youth within adult prisons for status offenses remove them within a span of two years (this timeframe was adjusted over time). The act also provided program grants to states, based on their youth populations, and created the Office of Juvenile Justice and Delinquency Prevention (OJJDP).
Through reauthorization amendments, additional programs have been added to the original Juvenile Justice and Delinquency Prevention Act. The following list highlights a few of these additions:
1977 - Programs were developed to assist children with learning disabilities who entered the juvenile justice system.
1984 - A new missing and exploited children program was added.
1984 - Strong support was given to programs that strengthened families.
1988 - Studies on prison conditions within the Indian justice system.
1990 - The OJJDP began funding child abuse training programs to instruct judicial personnel and prosecutors.
