Web Apps
Adult Redeploy Illinois (ARI) is housed at the Illinois Criminal Justice Information Authority (ICJIA), the state’s lead agency for justice system funding and research. ICJIA launched the Research Hub which provides a host of resources (publications, continuums, dashboards, datasets) to support data-driven decision-making for improved outcomes, including the web applications below. These apps are helpful to ARI sites in developing and implementing their local diversion programs and staying abreast of the latest research about community corrections, treatment in the justice systems, crime trends, and victimization.

This dashboard visualizes Illinois juvenile justice data from the years 2017 to 2022. This dashboard will be updated with 2023 and 2024 data upon availability of all data sources. In this dashboard, “juvenile” or “youth” refers to an individual under the age of 18. Users can filter the dashboard by five different juvenile justice system points—arrest, detention, informal probation, transfer to adult court, and confinement. Annual trends by data point are available in the dashboard, as well as a breakdown by county type (rural vs. urban). Arrest information is protected per our data sharing agreement with the Illinois State Police. Specific modifications have been made to arrest data.

Public Act 101-0024 ensured the permanent collection of Illinois traffic and pedestrian stop data by police departments. Each year, police departments submit their data to the Illinois Department of Transportation (IDOT). Per a Data Sharing Agreement, IDOT shares this data with ICJIA on an annual basis.
The purpose of this dashboard is to visualize Illinois traffic stop information. This dashboard contains Illinois traffic stop data from the year data collection began, 2004, to the most recent year of data we have received from IDOT—please refer to the “last updated” date. The information contained in this dashboard represents what was reported by the police officer as occurring during the stop. The dashboard can be filtered by different demographics—gender, race, age—as well as year, county, and police agency. Users can also view information about the stop itself, such as the day, time, and police shift it occurred, the reason for stop and result of stop, as well as if a search was conducted and contraband was found.
