"The National Juvenile Court Data Archive (Archive) houses the automated records of cases handled by courts with juvenile jurisdiction. The Archive was established by the Office of Juvenile Justice and Delinquency Prevention, within the U.S. Department of Justice, to promote access to automated juvenile court data sets for juvenile justice research and policymaking efforts. This web site was developed to inform researchers about the available data sets and the procedures for use and access." -- From Website
