Juvenile Court Statistics (JCS) uses data provided to the National Juvenile Court Data Archive by State and county agencies responsible for collecting and/or disseminating information on the processing of youth in juvenile courts. These data are not the result of a uniform data collection effort. They are not derived from a complete census of juvenile courts or obtained from a probability sample of courts. The national estimates presented in this Report are developed by using compatible information from all courts that are able to provide data to the Archive.
