Data Reports

Below are reports with juvenile justice system planning data.  The 2016 Juvenile Justice Planning Data – Statewide Report was released May 24, 2017.  The data in the newly released reports and the 2015 reports are organized by race/ethnicity and gender.   It is intended the data will further state and local collaborative policy and practice efforts to reduce the overrepresentation of minority youth in Iowa's juvenile justice system.  The reports contain data regarding juvenile population/student enrollment, in and out-of-school suspensions (removals), and select juvenile justice decision making points (complaints, allegations, diversions, petitions, and juvenile detention facility holds).  The data reports are part of an ongoing partnership by the Department of Human Rights, Division of Criminal and Juvenile Justice Planning and the Iowa State Court Administrator's Office to provide data, to continue engagement of collaboratives and key leadership, to encourage discussion, and to actively affect efforts to reduce juvenile justice system overrepresentation of minority youth.

DMC Matrices

As part of the reauthorization of the Juvenile Justice and Delinquency Prevention Act (JJDP Act), the federal Office of Juvenile Justice and Delinquency Prevention (OJJDP) designed matrices states are required to submit with their annual JJDP Act formula grant application. The matrices present major decision points and compare processing “rates” by race and ethnicity through the relative rate index. The "relative rate index" (RRI) is OJJDP's identified method to compare rates. If the processing rate for one race/ethnic category of youth is identical to that of another, the relative rate index is a "1."  Ultimately, state and local users of the matrices will need to examine the rates of each racial/ethnic group and consider what an "acceptable rate" is in addition to the relative rate. The data provided in the below matrices are “incident” rather than “case/youth” based.  In 2017, OJJDP modified the parameters for the matrices, and they are now being reported on a federal fiscal year.
