About the DMC Databook

What's new:

With the June 2015 update, the following new features have been added to the National DMC Databook:

  • DMC tables are now available for combinations of gender and race. These tables focus only on juvenile court stages as national estimates of juvenile arrests by race and gender are not currently available. Select the "by gender and race" option from the left menu.
  • Tables comparing males to females have been added using the OJJDP DMC matrix. Select the "by gender" option from the left menu.
NOTE: With the June 2015 update, national estimates of the youth population and juvenile court cases were updated to include data from 2013. The 2013 national juvenile arrest estimates have yet to be released. As such, all 2013 display tables will use the 2012 national arrest estimates.

The National Disproportionate Minority Contact (DMC) Databook is designed to give users an understanding of the Relative Rate Index (RRI) and an assessment of the levels of disproportionate minority contact at various stages of juvenile justice system processing at the national level. New users should review the sections entitled "What is an RRI?" and "Constructing an RRI Matrix". The first briefly discusses the benefits in using an RRI Matrix to investigate disproportionate minority contact within a jurisdiction. The second discusses how an RRI Matrix can be prepared using available information and the compromises that at times need to occur. For a more detailed discussion of these topics, users are encouraged to review Chapter One of the online Disproportionate Minority Contact Technical Assistance Manual.

In the National DMC Databook, users can review the raw counts and rates that characterize the processing of delinquency cases by the juvenile justice system and then study the RRI Matrix that helps to pinpoint and quantify the levels of racial disparity introduced at various decision points with the system. For those who need assistance, some possible interpretations of the most current RRI Matrices are given, as are interpretations of the trends in the level of disparity for each decision point. It is hoped that users can develop a better understanding of the RRIs from these interpretations and can apply this understanding when studying the many other RRIs that are available for review in this data dissemination tool or the RRIs developed locally to capture the nature of disproportionate minority contact in their own communities.
