Illinois Criminal JusticeWelcome 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.

There is a national opioid epidemic and one intervention to help those suffering from an opioid use disorder (OUD) is medication-assisted treatment (MAT). MAT is the use of medications in conjunction with behavioral therapy as part of a long-term treatment regimen. There are three main MAT medications used today—methadone, buprenorphine, and naltrexone. Research has shown MAT, in particular the use of methadone or buprenorphine, is considered an evidence-based practice to treat OUD. Studies indicate those in MAT have better outcomes than those who engage in therapy alone. This article provides an overview of MAT with a focus on use with criminal justice populations.
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.
Addressing street-level violence such as murders and aggravated assaults and batteries that occur on the public way and often involve firearms requires a multi-pronged approach. One effective model for addressing street violence, and, in particular, gang-related or group-involved street violence, is the Office of Juvenile Justice and Delinquency Prevention’s (OJJDP) Comprehensive Gang Prevention, Intervention, and Suppression Model. The model involves implementing complementary and coordinated prevention, intervention, and suppression activities in a single community. This article provides examples of evidence-based practices and programs that strengthen youth resilience and build social capital and work to reduce threats or perceived threats using the OJJDP model as a framework. The article also highlights how the model is enhanced when community stakeholders consider how trauma has impacted residents and those targeted by intervention and suppression efforts.
While more than half of individuals incarcerated in U.S. jails and prisons meet the diagnostic criteria for a substance use disorder, little is known about their misuse of prescription drugs. In this study, Authority researchers, in collaboration with WestCare Foundation Illinois, surveyed 573 state prisoners on prescription drug use to examine prevalence, accessibility, motivation for use, and effects. Forty-six percent of the sample reported using prescription drugs to get high and 20 percent used prescription drugs daily in the year before their incarceration.
In 2016, the Illinois Criminal Justice Information Authority contracted with Aeffect, Inc. to conduct a statewide victim needs assessment. The study was designed to guide the ICJIA victim services planning process and provide insight into the prevalence of victimization, needs of victims, and their receipt and satisfaction with services. Major findings of the assessment are outlined.
Over the past decade, federal, state, and local law enforcement have increasingly been called upon to identify and investigate human-trafficking offenses. Numerous efforts have been put in place to track incidents, arrests, and criminal offenses related to human trafficking. In response to directives from the William Wilberforce Trafficking Victims Protection Reauthorization Act (2008), the FBI added two new crime categories to the Uniform Crime Reporting Program (UCR) to capture commercial-sex acts and involuntary servitude. Additionally, in an effort to improve our understanding of the prevalence of human trafficking in the United States, state legislatures have begun to require the collection of data on human trafficking offenses identified by criminal-justice officials. However, despite the promises of standardized data from law enforcement about human trafficking, the numbers of reported human-trafficking offenses and arrests have been low. In this article, we examine official counts of human trafficking collected by criminal-justice-system data programs. We draw on data from a survey of state crime-reporting agencies and case studies of human trafficking crime reporting conducted in two U.S. states to explore the challenges that local police agencies face reporting human trafficking. Finally, we offer suggestions for improving officially reported data.
It is important for states to understand current drug and crime trends in order to be proactive. Local law enforcement can provide important contributions in identifying emerging drug and crime trends as frontline officers. To get the local law enforcement perspective, the Illinois Criminal Justice Information Authority administered a survey to Illinois police chiefs and county sheriffs to gain insight regarding drug trafficking in their jurisdiction. Eighty-three police chiefs and county sheriffs responded to the survey, most frequently identifying heroin and prescription drugs as the greatest drug threats in their jurisdictions. Methamphetamine was also reported as the greatest drug threat in the central and southern regions of Illinois. This article is a summary of key findings of the full report.
Synthetic drug use is a growing public health concern. Synthetics are often cheaper and more readily available than cannabis and amphetamines, making them attractive alternatives to other illicit drugs. In addition, the chemical formulas for these drugs are constantly changing, making them difficult to regulate, and their detection is limited in commonly used drug screenings. Authority researchers partnered with WestCare Foundation to survey 573 state prisoners on synthetic drug use to examine prevalence, accessibility, motivation for use, and effects. Thirty-six percent of respondents reported any synthetic drug use in their lifetime prior to incarceration. Findings suggested a proportion of the criminal justice population engages in synthetic drug use and the findings were consistent with other research on synthetic drug use.
Juveniles adjudicated delinquent for a sex offense can result in lifelong consequences, including sex offender registration. Further, there can be repercussions financially, emotionally, and socially for a juvenile and his/her family that extend throughout the individual’s life. Given the potential negative impact of sex offender registration, it is important to understand the implications of the registry within the larger context of youth development and juvenile justice. This report analyzes characteristics of youth arrested, detained, and admitted to corrections in Illinois in 2014 and associated trends from 2004 to 2014.
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.
