Crime

Chicago's crime rate in 2020 was 3,926 per 100,000 people. Chicago experienced major rises in violent crime in the 1920s, in the late 1960s, and in the 2020s. Chicago's biggest criminal justice challenges have changed little over the last 50 years, and statistically reside with homicide, armed robbery, gang violence, and aggravated battery. Chicago has a higher murder rate than the larger cities of New York and Los Angeles. However, while it has a large absolute number of crimes due to its size, Chicago is not among the top-25 most violent cities in the United States.

Murder rates in Chicago vary greatly depending on the neighborhood in question. The neighborhoods of Englewood on the South Side, and Austin on the West side, for example, have homicide rates that are ten times higher than other parts of the city. Chicago has an estimated population of over 100,000 active gang members from nearly 60 factions. According to reports in 2013, "most of Chicago's violent crime comes from gangs trying to maintain control of drug-selling territories," and is specifically related to the activities of the Sinaloa Cartel, which is active in several American cities. Violent crime rates vary significantly by area of the city, with more economically developed areas having low rates, but other sections have much higher rates of crime. In 2013, the violent crime rate was 910 per 100,000 people; the murder rate was 10.4 per 100,000 – while high crime districts saw 38.9 murders, low crime districts saw 2.5 murders per 100,000.

Chicago has a long history of public corruption that regularly draws the attention of federal law enforcement and federal prosecutors. From 2012 to 2019, 33 Chicago alderpersons 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 alderpersons took illegal campaign contributions in 2013. Most corruption cases in Chicago are prosecuted by the U.S. Attorney 's office, as legal jurisdiction makes most offenses punishable as a federal crime.
