This comprehensive "report draws on numerous national data collections to address the specific information needs of those involved with the juvenile justice system. The report presents important and, at times, complex information using clear, nontechnical writing and easy-to-understand graphics and tables. It is designed as a series of briefing papers on specific topics, short sections designed to be read separately from other parts of the report. The material presented here represents the most reliable information available for the 2010 data year on juvenile offending and victimization and the juvenile justice system. Given the breadth of material covered in this report, a data-year cutoff had to be established. We elected 2010 as a common anchoring point because all the major data sets required for the report were current through 2010 at the time we began writing. Although some newer data are now available, the patterns displayed in this report remain accurate" (p. iii). This report contains seven chapters: population characteristics; juvenile as victims; juvenile offenders; juvenile justice system structure and process; law enforcement and juvenile crime; juvenile offenders in court; and juvenile offenders in correctional facilities.
