About the DMC Databook

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.

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 disparity introduced at various decision points with the system. It is hoped that users can develop a better understanding of the RRIs 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.
