Violence Reduction - Victims of Homicides and Non-Fatal Shootings

Violence Reduction - Victims of Homicides and Non-Fatal Shootings

This dataset contains individual-level homicide and non-fatal shooting victimizations from 2016 to the present. Each row represents a single victimization, i.e., a unique event when an individual became the victim of a violent index crime. Each row does not represent a unique victim—if someone is victimized multiple times there will be multiple rows for each of those distinct events.

These classifications are slightly different from the Chicago Police Department’s (CPD) traditional Illinois Uniform Crime Reporting (IUCR) classifications of criminal incidents. "Fatal Shooting," "Non-Shooting Homicide," and "Non-Fatal Shooting" are not IUCR primary descriptions (IUCR primary descriptions do not specify type of injury). However, due to the severity of gun violence in Chicago, the City has chosen to depart slightly from IUCR primary descriptions used in this dataset to highlight injuries caused by guns.

The dataset is refreshed daily, but excludes the most recent complete day to allow CPD time to gather the best available information. Each time the dataset is refreshed, records can change as CPD learns more about each victimization, especially those victimizations that are most recent. The data on the Mayor's Office Violence Reduction Dashboard is updated daily with an approximately 48-hour lag. As cases are passed from the initial reporting officer to the investigating detectives, some recorded data about incidents and victimizations may change once additional information arises. Regularly updated datasets on the City's public portal may change to reflect new or corrected information.

A version of this dataset with additional crime types is available by request. To make a request, please email <a href="mailto:dataportal@cityofchicago.org?subject=Violence Reduction Victims Access Request">dataportal@cityofchicago.org</a> with the subject line: <b>Violence Reduction Victims Access Request</b>. Access will require an account on this site, which you may create at https://data.cityofchicago.org/signup.

Note: The definition of “homicide” (shooting or otherwise) does not include justifiable homicide or involuntary manslaughter. This dataset also excludes any cases that CPD considers to be “unfounded” or “noncriminal.” Officer-involved shootings are also excluded; when an officer discharges their weapon, a separate case report is generated using one of the following IUCR codes: 5060, 5103, 5104, 5140, 5141, 5142.

Note: The initial reporting officer usually asks victims to report demographic data. If victims are unable to recall, the reporting officer will use their best judgment. “Unknown” can be reported if it is truly unknown.
