CJJP staff provide a justice system information clearinghouse service to system officials and the general public.

CJJP also administers federal and state grant programs to fund local and state projects to prevent juvenile crime, provide services to juvenile offenders and otherwise improve Iowa's juvenile justice system. Annually, this funding is made available through competitive and allocation grant application procedures.

Adult Criminal and Juvenile Delinquency Data

Our Division receives requests from a variety of individuals needing statistics on adult criminal charges and/or convictions as well as juvenile delinquency-related data.
As a convenience to these individuals and the public, the Division of Criminal & Juvenile Justice Planning (CJJP) has launched two separate websites where that data can be accessed:

  • EZ Access to Adult Criminal Data website ( provides access to court disposed adult criminal charge and conviction data. Results are provided in aggregated, crosstab tables.
  • EZ Access to Juvenile Delinquency-related Data website ( provides access to juvenile delinquency data. Results are provided in aggregated, crosstab tables.

This information is provided through CJJPā€™s Justice Data Warehouse (JDW), a central repository of key criminal and juvenile justice information from the Iowa Court Information System (ICIS) and the Iowa Correctional Offender Network (ICON) system. The JDW is located on a platform within the Office of the Chief Information Officer and managed by CJJP.
The overall mission of the JDW is to provide the judicial, legislative and executive branches of State Government, and other entities, with improved statistical and decision support information pertaining to justice system activities.
