The Division of Juvenile Justice (DJJ) generates a variety of reports and statistical information through its research program. If you have questions about the kinds of information we make readily available, we urge you to carefully read through the following information before e-mailing a question or mailing a research request. Thank you for your interest in the DJJ.

The Research Division carries out the DJJ's research program using the following functions:

  • The youth information function; the Division manages the Department's Offender-based Information and Tracking System, develops projections for the Department's facility and parole populations, publishes reports on the DJJ's youthful offender population, and provides statistical information in response to requests from inside and outside the Department.
  • The research and evaluation function; the Division carries out short-term and long-term process and impact evaluations of the Department's rehabilitative programs, conducts research projects to enhance the classification of offenders according to their treatment needs and risks, conducts research designed to assess the Department's facility program needs, and provides research-based information to DJJ administrators, staff, and others outside the Department.

The DJJ Research Division provides information in three broad areas:

  1. Facility and parole population characteristics
  2. Population projections
  3. Research and evaluation reports
