Welcome to the Research & Analysis Unit of the Illinois Criminal Justice Information Authority

This site provides Illinois-specific criminal justice information and data in a way that's informative, interesting, and easy-to-navigate. Our goal is to offer a wide range of materials and resources that are useful to justice system practitioners, planners, researchers, students, and the general public.

ICJIA's Research & Analysis Unit also serves as the state's Statistical Analysis Center (SAC). This center is affiliated with and supported by the Justice Research and Statistics Association (JRSA), 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. Read more »
