Data were collected through a review of laws pertaining to juveniles. Analysis used a questionnaire developed in an earlier study. Subject areas covered were juvenile court structure, waiver to the adult criminal court, maximum age of juvenile court jurisdiction, and types of juveniles within the court's jurisdiction. Other subject areas included the custody process, place of detention, time and petition requirements, and disposition. Further subject areas were statutory references to the Interstate Compact on Juveniles and information on inspection provisions for juvenile facilities. The report reflects the law as of mid-1979. For each subject area, an introductory essay discusses general definitions and variations among States. A table presenting specific aspects of each State's juvenile codes follows. Notes and a bibliography listing 29 references are included. Appendixes list each State's laws referring to the interstate compact and to inspection and monitoring of facilities handling juveniles.
