Violence Reduction - Victim Demographics - Aggregated

Violence Reduction - Victim Demographics - Aggregated

This dataset contains aggregate data on violent index victimizations from 2016 to the present with a focus on those related to gun violence, such as fatal and non-fatal shootings. Index crimes are 10 crime types selected by the FBI (codes 1-4) for special focus due to their seriousness and frequency. This dataset includes only those index crimes that involve bodily harm or the threat of bodily harm and are reported to the Chicago Police Department (CPD). Each row is aggregated up to victimization type, age group, sex, race, and whether the victimization was domestic-related. Data is not broken out by year; victimization counts shown account for all years in the dataset (2016-present). In order to protect the privacy of victims, this dataset does not include any victimization counts of 3 or less.

These classifications are slightly different from CPD's 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: All identified businesses identified as victims in CPD data have been removed from this dataset.

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.”

Note: In some instances, the police department's raw incident level data and victim level data that were inputs into this dataset do not align on the type of crime that occurred; in those instances, this dataset reflects the most recent determination. When it is not possible to determine which victims are associated with the most recent crime determination, the dataset will show empty cells in the respective demographic fields (age, sex, race, etc.).

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.

Columns

NUMBER_OF_VICTIMSnumber_of_victimsnumber_of_victimsNumberThe number of victims matching the unique combination of all other columns.

In particular, CPD has historically recorded a victim’s sex rather than gender although has added an additional field for collecting gender as of January 2021.
RACEraceraceTextThe race of the victims. Victimization demographic data shown here are captured by CPD and limited to information included in the police report, which may not often be supported by individual self-identification including for race and ethnicity.
DOMESTIC_Idomestic_idomestic_iCheckboxIndicates whether the aggregated number of victimizations were domestic-related as determined by the initial reporting officer or the investigating detective.
AGEageageTextThe age of the victims grouped by decade.
