Crime in Chicago has been tracked by theChicago Police Department's Bureau of Records since the beginning of the 20th century.

The city's overall crime rate, especially theviolent crime rate, is higher than the US average.^[1][2][3]Gangs in Chicago have a role in the city's crime rate.^{[4][5][6][7][8]} Chicago gangs prefer to do business withIndiana gun stores because Indiana has significantly weaker laws thanIllinois.^[9][10][11]

The number of homicides in Chicago hit a 25-year high in 2021,^[12] but reached a five year low in 2024 with a continued downward trend into 2025.^[13][14]

Chicago saw a major rise in violent crime starting in the late 1960s. Murders in the city peaked in 1974, with 970 murders when the city's population was over three million, resulting in a murder rate of around 29 per 100,000, and again in 1992, with 943 murders when the city had fewer than three million people, resulting in a murder rate of 34 murders per 100,000 citizens.

After 1992, the murder count steadily decreased to 415 murders by the mid-2000s, a reduction of over 50 percent. In 2021, there were 804 homicides recorded,^[15] representing a murder rate of 29.6 per 100,000.^[16] The year of 2022 saw a decline in homicides, followed by another 15% decline in 2023, ending the year with a total of 617.

Chicago experienced major rises inviolent crime in the 1920s, in the late 1960s, and in the 2020s.^[17] a decline in overall crime in the 2000s,^[18] and then a rise in murders in 2016.^[19] Murder, rape, and robbery are common violent crimes in the city, and the occurrences of such incidents are documented by the Chicago Police Department and indexed in annual crime reports.^[20]

After adopting crime-fighting techniques in 2004 that were recommended by theLos Angeles Police Department and theNew York City Police Department,^[21] Chicago recorded 448homicides, the lowest total since 1965. This murder rate of 15.65 per 100,000 population was still above the U.S. average, an average which takes in many small towns and suburbs.^[22]

By 2010, Chicago's homicide rate had surpassed that of Los Angeles (16.02 per 100,000), and was more than twice that of New York City (7.0 per 100,000).^[23] By the end of 2015, Chicago's homicide rate rose to 18.6 per 100,000. By 2016, Chicago had recorded more homicides and shooting victims than New York City and Los Angeles combined.^[24] By the end of 2020, Chicago's homicide rate rose to 28 per 100,000.

Chicago's biggestcriminal justice challenges have changed little over the last 50 years, and statistically reside with homicide,armed robbery, gang violence, andaggravated battery.

Former Chicago Police SuperintendentGarry McCarthy said a pervasive "no-snitch code" on the street remains the biggest reason more murders aren't being solved in Chicago, adding, "We're not doing well because we're not getting cooperation [...] They don't feel protected when they come forward. They feel that police will throw them under a bus, and they still have to live in the neighborhood."^[56] By 2016, Chicago's murderclearance rate had dropped to only 21%, and itsdetective force had dwindled from 1,151 in 2009 to 863 as of July 2016.^[57][58] Warmer months have significantly higher murder rates, and over 70% of murders take place between 7 pm and 5 am.^[59][60]

In 2011, 83% of murders involved a firearm, and 6.4% were the result of a stabbing. 10% of murders in 2011 were the result of an armed robbery and at least 60% were gang or gang narcotics altercations. Over 40% of victims and 60% of offenders were between the ages of 17 and 25. 90.1% of victims were male. 75.3% of victims and 70.5% of offenders were African American, 18.9% were Hispanic (20.3% of offenders), and whites were 5.6% of victims (3.5% of offenders).^[59]

Murder rates in Chicago vary greatly depending on the neighborhood in question. Many of the predominantly African American neighborhoods on theSouth Side are impoverished, lack educational resources and noted for high levels of streetgang activity.^[61] The neighborhoods ofEnglewood on the South Side, andAustin on the West side, for example, have homicide rates that are ten times higher than other parts of the city.^[62]

Violence in these neighborhoods has had a detrimental impact on the academic performance of children in schools, as well as a higher financial burden for school districts in need of counselors, social workers, and psychiatrists to help children cope with the violence.^[63] In 2014,Chicago Public Schools adopted the "Safe Passage Route" program to place unarmed volunteers, police officers and firefighters along designated walking routes to provide security for children en route to school.^[64] From 2010 to 2014, 114 school children were murdered in Chicago.^[65]

Chicago Police Superintendent Garry McCarthy was terminated byRahm Emanuel following the fall out from theshooting of Laquan McDonald.^[66]

A gunshot wound tothe body's center of mass can quickly prove fatal without immediate medical attention due toblood loss andinternal injuries.^[67] In September 2015,University of Chicago Medicine and Sinai Health Systems announced a joint $40 million venture to convertHoly Cross Hospital into a Level 1trauma center on the South side, making some of Chicago's most violent neighborhoods less than five miles from high-quality care.^[68] Non-fatal gunshot victims in Chicago had an overall rate of occurrence of 46.5 per 100,000 from 2006 to 2012, with a demographic breakdown of 1.62 per 100,000 for whites; 28.72 for Hispanics, and 112.83 for blacks.^[69] It is estimated that the medical expenses associated withgun violence costs the city of Chicago $2.5 billion a year.^[70][71]

Chicago has been criticized for comparatively light sentencing guidelines for those found illegally in possession of a firearm. Most people convicted of illegal gun possession receive the minimum sentence, one year, aChicago Sun-Times analysis found, and serve less than half of the sentence because of time forgood behavior and pre-trial confinement. The minimum sentence for felons found in possession of a firearm is two years. Those charged with simple gun possession had an average of four prior arrests.Felons charged with prior gun related crimes will be faced with stricter sentencing as of a new bill proposed in 2017. Those charged with gun possession by a felon had an average of ten prior arrests.^[72]

In September 2015, an area and neighborhood of Chicago, West Garfield Park, was named "America'smass shooting capital", citing 18 occasions in 2015 in which at least four people were shot in a single incident.^[73] In 2016, the number of murders soared to 769.^[19] August 2016 marked the most violent month Chicago had recorded in over two decades with 92 murders, included the murder of Nykea Aldridge, cousin of NBA starDwyane Wade.^[24][74] Chicago's 2016 murder and shooting surge has attracted national media attention fromCNN,The New York Times,USA Today,Time magazine andPBS.^{[75][76][77][78][79]} FilmmakerSpike Lee's 2015 release,Chi-Raq, highlights Chicago's gun violence using a narrative inspired by the Greek comedyLysistrata.^[80]

In 2017, the number of homicides fell to 653,^[19] dropping to 561 in 2018^[81] and 492 in 2019. Chicago's deadliest day since reliable digital records began in 1991, was on May 31, 2020, with 18 murders committed. That day was part of a three-day weekend that had 85 shootings, and 24 murders, the all-time highest number killed on a Chicago weekend.^[82] Reports indicate that the victims were of various ages and occupations, but mostly black. The violence was framed by theGeorge Floyd protests, but researchers said it was unheard of and unable to be contextualized. The city's second-deadliest day had 13 murders, and occurred in 1991 shortly after digital records were introduced. There is no deadlier day recorded in the past 60 years, but records prior to 1991 may be unreliable.^[83]

The seventy-seven Chicago community areas were defined cooperatively by the U.S. Census Bureau and the University of Chicago Department of Sociology following the 1920 Census. Although there have been substantial changes in population and infrastructure since then, the community areas remain the most widely used geographic units by Chicago planning agencies, advocacy groups, and service providers.

The table below shows population, crime totals and per capita crime rates by community area for 2020, the most recent Census year.

Chicago has an estimated population of over 100,000 active gang members from nearly 60 factions.^[125][126]Gang warfare and retaliation is common in Chicago. Gangs were responsible for 61% of the homicides in Chicago in 2011.^[59]

Former Chicago Police Superintendent Garry McCarthy blames Chicago's gang culture for its high rates of homicide and other violent crime, stating "It's very frustrating to know that it's like 7% of the population causes 80% of the violent crime...The gangs here are traditional gangs that are generational, if you will. The grandfather was a gang member, the father's a gang member, and the kid right now is going to be a gang member."^[127]

Mayor Rahm Emanuel disbanded the Chicago Police Department'santi-gang unit in 2012 in order to focus onbeat patrols, which he said would have a more long-term solution to violence than anti-gang units.^[128][129]

As many as 70 active and inactive Chicago street gangs with 753 factions have been identified.^[130][131] Some of the gangs that contribute most of the crime on the streets of Chicago:

• Gangster Disciples
• Vice Lords
• Black P. Stones
• Latin Kings
• Black Disciples
• Maniac Latin Disciples
• Spanish Cobras
• Almighty Saints
• Spanish Gangster Disciples
• Four Corner Hustlers
• Norridge Hearts

Detailed analysis of the homicides timeline by month show that homicides (of all races) went up right after Martin Luther King was killed in 1968 (still for reasons unknown). However, Hispanic-on-Hispanic homicides, did not notably start until the summer of 1971, due to the Latin Kings gang election meetings.^[132] However, this claim can't be immediately proven, as homicides by race are not made public for those time periods.

Chicago has a long history of publiccorruption that regularly draws the attention of federal law enforcement and federal prosecutors.^[133] Chicago's political landscape has been firmly under the control of theDemocratic Party for over 85 years and has been widely described as apolitical machine.^{[134][135][136][137]} In the 1980s, the FBI'sOperation Greylord uncovered massive and systemic corruption in Chicago's judicial system. Greylord was the longest and most successfulundercover operation in the history of theFBI, and resulted in 92 federal indictments, including 17 judges, 48 lawyers, eight policemen, ten deputy sheriffs, eight court officials, and one state legislator. Nearly all were convicted on a variety of charges includingbribery,kickbacks,fraud,vote buying,racketeering, anddrug trafficking.^{[138][139][140]}

The late 1980s and 1990s saw further efforts by the FBI to prosecute Chicago's public crime syndicates. Operation Incubator obtained about a dozen convictions or guilty pleas, including those from five members of the City Council and an aide to former MayorHarold Washington.^[141] Later Operation Gambat brought a wide range of charges against a Chicago judge, a state senator, an alderman, and two others relating to corruption in theCook County Circuit Court, theIllinois Senate, and theChicago City Council. Four were convicted and a fifth died during trial.^[142] The most extensive operation by the FBI of the 1990s,Operation Silver Shovel, sought to uncover corruption within Chicago labor unions, organized crime, and other city government officials. Operation Silver Shovel resulted in the conviction of six Chicagoaldermen and a dozen other local officials on a wide range of corruption related charges.^{[142][143][144]}

From 2012 to 2019, 33 Chicago aldermen were convicted on corruption charges, roughly one third of those elected in the time period. A report from the Office of the Legislative Inspector General noted that over half of Chicago's elected alderman took illegal campaign contributions in 2013.^[145] In 2015, mayor appointedBarbara Byrd-Bennett, the CEO ofChicago Public Schools, was convicted in a $23 million kickback scheme and was sentenced to seven and a half years in prison.^[146] In addition to the Bennett conviction, a joint investigative report issued by the Office of the Inspector General and federal authorities documented widespread corruption within Chicago Public Schools in 2015. The audit noted the criminalshakedown of a CPS vendor, a recordsforgery scheme by a principal, numerous instances of employees abusing CPS's tax-exempt status to purchase personal items at big-box retailers, illegally using taxpayer-funded resources to campaign for political causes and stealing from taxpayer-funded accounts intended for purchasing student materials.^[147]

A 2015 report released by theUniversity of Illinois at Chicago's political science department declared Chicago the "corruption capital of America", citing that the Chicago-based Federal Judicial District for Northern Illinois reported 45 public corruption convictions for 2013 and a total of 1,642 convictions for the 38 years since 1976 when theU.S. Department of Justice began compiling the statistics. UIC Professor and former Chicago aldermanDick Simpson noted in the report that "To end corruption, society needs to do more than convict the guys that get caught. A comprehensive anti-corruption strategy must be forged and carried out over at least a decade. A new political culture in which public corruption is no longer tolerated must be created".^[148][149]

Examples of other high-profile Chicago political figures convicted on corruption related charges includeRod Blagojevich,Jesse Jackson Jr.,Isaac Carothers,Arenda Troutman,Edward Vrdolyak,Otto Kerner, Jr.,Constance Howard,Fred Roti andDan Rostenkowski.

In October 2015, the FBI announced that Michael Anderson would take over for a retiring Robert Holley asSpecial Agent in Charge of the Chicago Bureau. Anderson, a corruption veteran who wrote the FBI Public Corruption Field Guide, called Chicago "target rich" for cases in an interview with theChicago Tribune. Anderson commands a team of 850 agents in Chicago along with analysts and support staff.^[150][151]

Most corruption cases in Chicago are prosecuted by theUS Attorney's office, as legaljurisdiction makes most offenses punishable as a federal crime.^[152] The current US Attorney for the Northern district of Illinois is Zachary T. Fardon.^[153] In a press conference in January 2016, in the wake of the conviction of formerChicago City Hall official, John Bills, for taking $2 million in bribes, Fardon commented "Public corruption [in Chicago] is a disease and where public officials violate the public trust, we have to hold them accountable. And I do believe that by doing so, it sends a deterrent message."^[154][155]

During theProgressive Era, the first juvenile system was created by Chicago officials and, to make the court system more organized and specific, specialized courts, like those for domestic disputes, were created.^[156] Not only did the court and corrections systems change, there was also a change in policing. Divisions and squads became specialized on particular types of crime. The courts began to incorporate specialists, like scientists and psychologists, to make the trial and evidence more reliable and trustworthy.^[156]

Chicago was among the first U.S. cities to create an integrated emergency-response center to coordinate the response to natural disasters, gang violence, and terrorist attacks. Built in 1995, the center is integrated with more than 2,000 cameras, communications with all levels of city government, and a direct link to theNational Counterterrorism Center. Police credited surveillance cameras with contributing to decreased crime in 2004.^[157]

In 2003, the Chicago Police Department began installing POD's (Police Observation Devices) in high-crime areas. The cameras are able to rotate 360 degrees and zoom to a fine level of detail. The devices are also bulletproof, operable in any weather condition, record continuously and switch into night-vision mode after dark. POD's are used to monitor street crime and direct police deployment. Data from the cameras is wirelessly transmitted to the Chicago Crime Prevention and Information Center (CPIC) which can individually control any camera.^[158][159] Over 20,000 cameras currently operate in Chicago. In addition to PODs, colloquially referred to as "blue-light cameras", the city has added general surveillance cameras toCTA stations, buses,Chicago Housing Authority buildings, public buildings and schools.^[160] This has prompted harsh criticism fromprivacy advocates and theACLU who called the program "A pervasive and poorly regulated threat to our privacy".^[161]

The Chicago Police Department has also been criticized for its liberal use of the controversial "stop-and-frisk" policy.^[162] For decades, the policy gave officers much more autonomy to conduct stops andpat-downs if there exists areasonable suspicion that a suspect might bearmed and dangerous.^[163][164] The ACLU has claimed that the policy unfairly targets African Americans, who accounted for nearly 75% of those stopped in 2014, even though they account for a third of the city's population.^[165] The Chicago Police Department confiscated almost 7,000 firearms in 2014, about 583 per month.^[166] The stop-and-frisk policy was largely abandoned by CPD in early 2016.^[164]

Because theChicago Police Department tallies data differently than police in other cities, the FBI often does not accept its crime statistics^{[citation needed]}. Chicago police officers record all criminal sexual assaults, as opposed to only rape^{[citation needed]}. They count aggravated battery together with the standard category of aggravated assault^{[citation needed]}. As a result, Chicago is often omitted from studies such asMorgan Quitno's annual "Safest/Most Dangerous City" survey, which relies on FBI-collected data.^[167]

The Chicago Police Department's CLEAR (Citizen Law Enforcement Analysis and Reporting) system is a web application enabling the public to search the Chicago Police Department's database of reported crime. Individuals are able to see maps, graphs, and tables of reported crime. The database contains 90 days of information, which can be accessed in blocks of up to 14 days. Data is refreshed daily. However, the most recent information is always six days old.

The police use "guardian-like" intervention, a method relying on information from an individual's criminal history in order to predict the likelihood of becoming a victim or perpetrator of violence, to "build public trust and legitimacy."^[168]

CPD tallied 22 police-involved shootings in 2015, eight of which resulted in fatalities.^[169] Fatality cases involving an African American perpetrator often gave rise to amedia sensation, both in Chicago and elsewhere.^[170] In December 2015, the US Department of Justice opened acivil rights investigation of the Chicago Police Department in the aftermath of the Laquan McDonald case. The "pattern and practice" probe evaluated the use of force, deadly force, accountability and tracking procedures of the department. A 190-page report issued in April 2016 deemed the Chicago Police Department a racist organization. Chairman of the ChicagoFraternal Order of Police, Dean Angelo called the report "totally biased" and "utterly ridiculous".^{[171][172][173][174]}

2016's surge in murders and shootings, coupled with a decline in gun seizures, led former Police Superintendent John Escalante to express concerns in March 2016 that officers might be hesitant to engage inproactive policing due to fear of retribution. Officers anonymously reported to theChicago Sun-Times that they have been afraid to make investigatory stops because the Justice Department and American Civil Liberties Union of Illinois have been scrutinizing police practices. Data of the supposed pullback was reflected with an 80 percent decrease in the number of street stops that officers made since the beginning of 2016. Dean Angelo has claimed that part of the problem is politicians and groups like the ACLU who don't know much about policing, and yet are "dictating what police officers do".^{[175][176][177]}

Professors Paul Cassell and Richard Fowles at the University of Utah later analyzed the 2016 Chicago homicide "spike" and concluded that the most likely cause was a consent decree entered into by the American Civil Liberties Union (ACLU) with the Chicago Police Department restricting stop and frisks. Cassell and Fowles concluded that 239 additional victims were killed and 1129 additional shootings occurred in 2016 because of the reduction in stop and frisks.^[178] This study, however, failed to identify such spikes in the large number of other cities subject to similar consent decrees,^[179] leading to questions about whether they had really identified a causal relationship.

In 2014 and 2015,Chicago Magazine andThe Economist conducted investigations into theCompStat data reporting of crime statistics for the city and reported irregularities. In addition, an audit conducted byChicago's Office of the Inspector General found significant problems in the accuracy of CPD's crime data.

According toChicago Magazine, superiors often pressure officers to under-report crime. An unnamed police source quoted in the magazine says there are "a million tiny ways to do it", such as misclassifying and downgrading offenses, counting multiple incidents as single events, and discouraging residents from reporting crime. The police department has responded that their statistics are generally accurate and that the discrepancies can be explained by differences in theUniform Crime Reporting used by theFBI and CompStat.^{[180][181][182][183][184]}

The city of Chicago has one of the highest murder rates among large cities. Despite generally strict gun laws compared to neighboring areas, there are still many illegal guns in Chicago. It is estimated that 80% of homicides in Chicago are committed with firearms.^[185] Chicago recorded 780 murders in 2020. This figure represents an increase of more than 55% over 2019.^[186] On theFourth of July weekend 2021, at least 100 people, mostly African-American, were shot, 18 of them fatally. Murders for 2021, are trending higher than 2020.^[187]

Chicago has a ban on guns designated as "assault weapons" andlaser sights.^[188][189] Additionally, under Illinois law, to own a firearm one must possess afirearms owners’ identification (FOID) card, undergo a background check, and wait 72 hours before taking possession of a purchased firearm.^[190][191] Lost or stolen guns must also be reported to law enforcement within 72 hours.^[192] There are currently no gun stores in the Chicago city limits and Federal firearms laws already make it illegal to buy firearms out of state without an FFL transfer and background check from that state. Access to guns is likely occurring via neighboring Indiana,a state with lax gun laws, and the many other areas through already illegal straw purchases.^[193]

About 7000 guns are recovered by Chicago police each year at crime scenes. An estimated 45% of these guns are bought by straw buyers in states with lax gun laws, namelyIndiana.^[194] In April 2021, the City of Chicago filed a lawsuit against Westforth Sports ofGary, Indiana, alleging that it consistently ranks as one of the highest suppliers of guns used in crimes. The city claims that during the period from 2009 to 2016, 850 recovered guns were originally purchased from Westforth Sports.^[195]
