Welcome to the Research & Analysis Unit of the Illinois Criminal Justice Information Authority. The Research & Analysis Unit serves as Illinois’ Statistical Analysis Center (SAC). State SACs provide objective analysis of criminal justice data for informing statewide policy and practice. The Illinois SAC is affiliated with and supported by the Justice Research and Statistics Association, a national nonprofit organization that promotes collaboration and exchange of information among state SACs, and acts as a liaison between state agencies and the U.S. Department of Justice.
The Center for Justice Research and Evaluation conducts applied research and evaluation projects that examine critical criminal and juvenile justice topics and criminal justice program implementation and outcomes in Illinois. Staff collect data through multiple research methods, conduct advanced statistical analyses, and summarize findings in publications that aim to inform policy and practice. The center also conducts presentations and offers technical assistance to help state and local programs and initiatives use data to inform and improve their work.
The Center for Criminal Justice Data and Analytics continually collects, analyzes, reports on, and disseminates crime and risk factor statistical information for strategic planning, policy decisions and public education. Staff has developed a repository of these data on the ICJIA website, along with various online tools for data display and analysis. In partnership with the State Police, the Center is responsible for the dissemination of state criminal history record information (CHRI) data for research purposes, including in-house analytic use. The Center provides technical assistance in statistical methods, database design, data analysis and presentation.
The Center for Sponsored Research & Program Development secures experts in the field to conduct research and evaluate programs that inform policy, support evidence-based practices, and guide decision-making. Staff review and select programs and other priority criminal justice-related topics viable for evaluation and further research. Researchers are selected through a competitive process and are awarded federal grant subcontracts to conduct studies. The center also provides technical assistance to programs supported with Authority-administered grant funds as they refine program objectives, develop data collection tools, and assess program performance.
The Center for Victim Studies designs and conducts research examining the nature and scope of victimization in Illinois and evaluates programs that address victim needs. Center staff use a variety of research methods and analyses to explore victimization and victim services in order to improve policy, programming, and practice throughout the state. The center also coordinates presentations and disseminates reports, translating promising research into implications for policy and practice for stakeholders and victim service providers. Staff also provide technical assistance to help victim service programs collect data to inform how to best meet the multifaceted needs of victims. Finally, staff manage the InfoNet System, a web-based data collection and reporting system used by more than 100 victim service providers in Illinois. The system is one of only a few known central repositories in the country for statewide, standardized victim service data. Click here to learn more about InfoNet.

Juvenile Justice in Illinois, 2015, provides a statistical overview of the juvenile justice system in Illinois across four decision points in which data were available: arrest, detention admissions, active probation caseloads, and new sentence admissions to corrections. Statewide and regional figures are provided with rates spanning from 2011 to 2015. In addition, population, demographic, and offense type information is provided for decision points in which data were available in 2015. Overall, rates for arrest, active probation caseload, detention admissions, and new sentence admissions to corrections have decreased between 2011 and 2015; however, the Central and Southern regions had slight increases in detention admission rates.
With support from the U.S. Department of Justice, Bureau of Justice Statistics, ICJIA has developed several data analysis and dissemination tools to give users convenient and flexible ways to access and interact with ICJIA’s extensive criminal justice and associated risk factor data holdings.
The Criminal Justice Data Profiles tool offers criminal justice indicators that allow users to create county, judicial circuit, and statewide profiles. These profiles may be used to inform planning and policy decisions.
Criminal Justice Data Profiles
The Criminal History and Recidivism Tool provides information on the
patterns of prior criminal history of various cohorts of persons sentenced
to prison in Illinois, and their long-term recidivism rates upon release. Tables and charts display several types of
information: demographic information on the selected group of interest; the number and types of prior arrests, convictions,
probation and prison sentences; and post-release recidivism rates based on multiple types of criminal justice events and demographic categories.
Criminal History and Recidivism Tool
The Single Map Analysis Tool is useful for those interested in a visual snapshot
of how Illinois counties compare on various crime and criminal justice indicators.
The tool displays this information in two interactive formats; as an Illinois map,
and as corresponding trend lines over the previous ten years. Users can select any number
of counties, regions or judicial circuits for comparison.

The Scatter Plot Analysis Tool allows users to compare the relationship
between two different criminal justice indicators within a county,
and determine how all Illinois counties rank on that joint set of crime statistics
or criminal justice indicators. The tool displays this information in several
interactive formats; as Illinois maps and as a corresponding scatter plot
showing correlations for all counties or custom sets of counties in Illinois.

These tools come with a variety of built-in Help features to assist users as they navigate the unique analysis functions.
