Most Dangerous Cities in Illinois

FBI UCR Highest-Crime Snapshot: Illinois

Illinois's 50 highest-crime cities for 2024 range from Danville at the top with a violent crime rate of 1684.3/100K down to Alsip at 289.8/100K, all sitting above most US municipal averages. The list draws on FBI Uniform Crime Reporting (UCR) Program Table 8 submissions and restricts inclusion to cities of 10,000 residents or more so that per-capita rates reflect enough underlying offenses to be statistically meaningful. Across these 50 Illinois cities the average violent crime rate reaches 537 per 100,000 residents, a figure that typically exceeds the US national violent crime benchmark by a wide margin.

At the top of the ranking, Danville recorded 470 violent crimes and 1,584 property crimes against a reporting population of 27,905 in 2024. That produces a property crime rate of 5676.4 per 100,000 residents alongside the 1684.3/100K violent rate, with both Part I crime categories elevated compared to state and national benchmarks. The five most dangerous Illinois cities on this list are Danville, Peoria, Chicago Heights, Rockford, Carbondale, each submitting Part I offense counts to the FBI UCR Program for 2024.

Elevated per-capita rates can reflect multiple factors beyond raw crime volume: small reporting populations amplify year-to-year rate volatility, transient or tourist populations dilute resident denominators, and municipal boundaries sometimes exclude higher-income suburbs that would otherwise balance the total. UCR figures also reflect offenses reported to and submitted by local law enforcement and can miss unreported crime entirely, so rankings measure visible, recorded crime rather than absolute community conditions. Readers comparing these cities with others across Illinois can use the A-F safety grades page or national rankings to contextualize how 2024 figures stack up against peers nationwide.

High-crime rankings draw attention, but they demand even more care than safest-cities lists. A city near the top of this table is not uniformly dangerous; offenses concentrate in particular places and times, and a citywide rate averages very different neighborhoods into one number. Cities with thorough police reporting can appear worse than places that record fewer incidents, which effectively penalizes transparency with a harsher-looking statistic. Population size matters too: a mid-sized city with a cluster of offenses can post a startling per-capita figure that a larger city would absorb. Use this ranking to ask why a rate is elevated and how it has changed over time, not to label an entire community, and always check the raw counts and the reporting agency before repeating a figure.
