This dataset contains individual-level homicide and non-fatal shooting victimizations, including homicide data from 1991 to the present, and non-fatal shooting data from 2010 to the present (2010 is the earliest available year for shooting data). This dataset includes a "GUNSHOT_INJURY_I " column to indicate whether the victimization involved a shooting, showing either Yes ("Y"), No ("N"), or Unknown ("UKNOWN.") For homicides, injury descriptions are available dating back to 1991, so the "shooting" column will read either "Y" or "N" to indicate whether the homicide was a fatal shooting or not. For non-fatal shootings, data is only available as of 2010. As a result, for any non-fatal shootings that occurred from 2010 to the present, the shooting column will read as “Y.” Non-fatal shooting victims will not be included in this dataset prior to 2010; they will be included in the authorized-access dataset, but with "UNKNOWN" in the shooting column.

Each row represents a single victimization, i.e., a unique event when an individual became the victim of a homicide or non-fatal shooting. 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.

The dataset is refreshed daily, but excludes the most recent complete day to allow the Chicago Police Department (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 dataportal@cityofchicago.org with the subject line: Violence Reduction Victims Access Request. Access will require an account on this site, which you may create at https://data.cityofchicago.org/signup.

How does this dataset classify victims?

The methodology by which this dataset classifies victims of violent crime differs by victimization type:

Homicide and non-fatal shooting victims: A victimization is considered a homicide victimization or non-fatal shooting victimization depending on its presence in CPD's homicide victims data table or its shooting victims data table. A victimization is considered a homicide only if it is present in CPD's homicide data table, while a victimization is considered a non-fatal shooting only if it is present in CPD's shooting data tables and absent from CPD's homicide data table.

To determine the IUCR code of homicide and non-fatal shooting victimizations, we defer to the incident IUCR code available in CPD's Crimes, 2001-present dataset (available on the City's open data portal). If the IUCR code in CPD's Crimes dataset is inconsistent with the homicide/non-fatal shooting categorization, we defer to CPD's Victims dataset. For a criminal homicide, the only sensible IUCR codes are 0110 (first-degree murder) or 0130 (second-degree murder). For a non-fatal shooting, a sensible IUCR code must signify a criminal sexual assault, a robbery, or, most commonly, an aggravated battery. In rare instances, the IUCR code in CPD's Crimes and Victims dataset do not align with the homicide/non-fatal shooting categorization:

1. In instances where a homicide victimization does not correspond to an IUCR code 0110 or 0130, we set the IUCR code to "01XX" to indicate that the victimization was a homicide but we do not know whether it was a first-degree murder (IUCR code = 0110) or a second-degree murder (IUCR code = 0130).
2. When a non-fatal shooting victimization does not correspond to an IUCR code that signifies a criminal sexual assault, robbery, or aggravated battery, we enter “UNK” in the IUCR column, “YES” in the GUNSHOT_I column, and “NON-FATAL” in the PRIMARY column to indicate that the victim was non-fatally shot, but the precise IUCR code is unknown.

Other violent crime victims: For other violent crime types, we refer to the IUCR classification that exists in CPD's victim table, with only one exception:

1. When there is an incident that is associated with no victim with a matching IUCR code, we assume that this is an error. Every crime should have at least 1 victim with a matching IUCR code. In these cases, we change the IUCR code to reflect the incident IUCR code because CPD's incident table is considered to be more reliable than the victim table.

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 not included.

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.

Note: In some instances, CPD'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 attempts to correct mismatches between incident and victim specific crime types. When it is not possible to determine which victims are associated with the most reliable crime determination, the dataset will show empty cells in the respective demographic fields (age, sex, race, etc.).

Note: Homicide victims names are delayed by two weeks to allow time for the victim’s family to be notified of their passing.

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.

Note: This dataset includes variables referencing administrative or political boundaries that are subject to change. These include Street Outreach Organization boundary, Ward, Chicago Police Department District, Chicago Police Department Area, Chicago Police Department Beat, Illinois State Senate District, and Illinois State House of Representatives District. These variables reflect current geographic boundaries as of November 1st, 2021. In some instances, current boundaries may conflict with those that were in place at the time that a given incident occurred in prior years. For example, the Chicago Police Department districts 021 and 013 no longer exist. Any historical violent crime victimization that occurred in those districts when they were in existence are marked in this dataset as having occurred in the current districts that expanded to replace 013 and 021."

In 2023, the FBI reported that there were 9,284 Black murder victims in the United States and 7,289 white murder victims. In comparison, there were 554 murder victims of unknown race and 586 victims of another race. Victims of inequality? In recent years, the role of racial inequality in violent crimes such as robberies, assaults, and homicides has gained public attention. In particular, the issue of police brutality has led to increasing attention following the murder of George Floyd, an African American who was killed by a Minneapolis police officer. Studies show that the rate of fatal police shootings for Black Americans was more than double the rate reported of other races. Crime reporting National crime data in the United States is based off the Federal Bureau of Investigation’s new crime reporting system, which requires law enforcement agencies to self-report their data in detail. Due to the recent implementation of this system, less crime data has been reported, with some states such as Delaware and Pennsylvania declining to report any data to the FBI at all in the last few years, suggesting that the Bureau's data may not fully reflect accurate information on crime in the United States.

In 2023, around 2,444 homicide victims in the United States were aged between 20 and 24 years old. A further 2,362 murder victims were between the ages of 30 and 34 years old. Most murder victims in the United States in 2023 were between the ages of 17 and 54 years old.

As of December 31, the U.S. police shot 1,173 people to death in 2024. In 2023, 1,164 people were shot to death by police in the United States. Police treatment Since as early as the 18th century, police brutality has been a significant issue in the United States. Black Americans have been especially marginalized by police officers, as they have faced higher rates of fatal police shootings compared to other ethnicities. Disparities also exist in perceptions of police treatment depending on ethnicity. A majority of Black Americans think that Black and White people do not receive equal police treatment, while more than half of White and Hispanic Americans think the same. Police reform The upsurge in Black Lives Matter protests in response to the killing of Black Americans as a result of police brutality has created a call for police reform. In 2019, it was found that police killings decreased by a quarter in police departments that implemented a policy that requires officers to use all other means before shooting. Since the killing of George Floyd in May 2020, 21 states, including New York and California, have passed bills that focused on police supervision.

July 2024 saw an incredibly close assassination attempt on former President Donald Trump while he was on the campaign trail for the 2024 presidential election. While speaking to his audience, a bullet whizzed past Trump's head, nicking him on the ear and drawing blood in the process, before the Secret Service escorted him to safety. One spectator was killed while shielding family members from the gunfire, and two more were shot but survived, before the perpetrator was shot and killed by security services. Throughout U.S. history, there have been numerous plots and attempts to assassinate U.S. presidents. The first known case was a failed attempt on Andrew Jackson's life in 1835, where both the assassin's guns misfired due to moisture in the air and Jackson then beat the culprit into submission with his cane. More recent attempts include separate, high-profile cases in October 2018, where sixteen bombs were sent via mail to prominent Democrats (including presidents Obama and Clinton), Trump critics, and news outlets, while another culprit sent letters laced with ricin to President Trump and senior U.S. military figures. Throughout history, the majority of these plots have been uncovered or prevented, however several have come close to achieving their aims and four have resulted in the successful assassination of a sitting president. Successful attempts The first successful assassination occurred in 1865, when Confederate sympathizers and spies plotted to kill the three highest-ranking figures in the Union, in an effort to re-ignite the American Civil War. Of the three targets, only Lincoln was assassinated after being shot in the head by John Wilkes Booth. Lincoln died within 12 hours of being shot, which was much sooner than the second presidential assassination, where James Garfield took almost four months to eventually die from his wounds after being shot in a train station in 1881. The third U.S. president to be assassinated was William McKinley, who was shot twice while meeting members of the public just six months into his second term. The attempt was not immediately fatal and McKinley was even able to dissuade bystanders from killing his attacker, however, one of the bullets was never found and McKinley passed away one week after the attack. The most recent U.S. president to have been assassinated was John F. Kennedy, who was shot by former marine and defector to the Soviet Union, Lee Harvey Oswald. Oswald shot Kennedy from the sixth floor of a nearby warehouse during a public motorcade in Dallas, Texas in 1963, and Kennedy died almost immediately. Although official investigations, forensic tests and eyewitness accounts corroborate the official story that Oswald acted alone, a high number of conspiracy theories surround the event, and a large share of the U.S. population believes that the assassination is part of a larger plot or cover-up, orchestrated by either the CIA, mafia, or foreign entities (among other theories). Close calls While on the 1912 campaign trail, former president Theodore Roosevelt was shot in the chest before giving a speech. Roosevelt knew that the injury was not fatal, and proceeded to deliver an 84 minute speech before seeking medical attention. In 1981, a gunman shot six bullets at Ronald Reagan as he was meeting a crowd outside a Washington hotel, injuring the president and three others in the attack. One bullet had ricocheted off the side of a car, punctured the president's lung, and caused severe internal bleeding. The president almost died en route to the hospital, but doctors were able to stabilize him and remove the bullet; Reagan returned to the White House less than two weeks later. Another close call was where a gunman fired shots at President-Elect Franklin D. Roosevelt's car in 1933, missing the President but killing the Mayor of Chicago in the attack. Coincidentally, the only female culprits in these attempts both tried to assassinate President Gerald Ford, in two unrelated attacks in California in September, 1975. The first (who was a member of the Manson Family) was stopped before she could get a shot off at the president, while the second was restrained after shooting twice and injuring one bystander -Ford was unharmed in both attacks. Another near miss was an unsuccessful attempt on Abraham Lincoln's life nine months before his successful assassination; the bullet went through his distinctive, stovepipe hat as he was riding to his summer cottage one evening. The only attempt included here that did not involve a firearm and did not take place in the United States was when a grenade was thrown on stage in Tbilisi, Georgia, as George W. Bush was making a speech there in 2005. Although the pin had been removed, the handkerchief used to conceal the grenade was wrapped too tightly around it for the lever for it to detach; nobody was injured in this attempt; however, the culprit did kill one agent as he was being arrested two month...
