Division of Criminal & Juvenile Justice Planning

The Division of Criminal and Juvenile Justice Planning (CJJP) is within the Department of Human Rights and was established through the provisions of Iowa Code Chapter 216A, Subchapter 9. CJJP is the Iowa Statistical Analysis Center (SAC), a member of the Justice Research and Statistics Association (JRSA), and carries out research, policy analysis, program development and data analysis activities to assist policy makers, justice system agencies and others to identify issues of concern and to improve the operation and effectiveness of Iowa's justice system. 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.

CJJP carries out its duties under the oversight of the Justice Advisory Board and the Iowa Juvenile Justice Advisory Council.  Administrative Rules governing CJJP operations and grant programs can be found in Section 428 of the Iowa Administrative Code.

The following report provides recommendations that 

focus on four areas related to adolescents—education, health, child welfare, and juvenile justice—and emphasizes the importance of youth engagement to solve problems, develop partnerships, and re-imagine/redesign systems to further support for adolescents. 

“Adolescence” can be defined as the period between child- and adulthood, beginning with the onset of puberty to the mid-20’s, and is divided into four age groups:

  • Early Adolescence (10-12)
  • Middle Adolescence (13-15)
  • Late Adolescence (16-18)
  • Young Adulthood (19-25)

The 411-page report provides multiple recommendations for capitalizing on opportunities to address inequities that undermine the well-being of many adolescents.  This and other research will be used to guide stakeholders in the future development of policies and legislation related to this age group.


Are you looking for adult criminal or 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 CJJP’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.
