How much crime is reported in Joliet?
In 2024, law enforcement reported 527 violent and 1,874 property offenses in the Joliet jurisdiction — a violent-crime rate of 350.0 per 100,000, about even with the U.S. estimate of 359.1.
Reported offenses known to law enforcement from the FBI Uniform Crime Reporting Program (CIUS Table 8), 2024. Figures describe the FBI agency jurisdiction: Joliet — an FBI jurisdiction population of 150,569, versus the Census place population of 152,241. The rate per 100,000 is the FBI's own (count ÷ that jurisdiction population), never divided by the Census place figure. These are reported crimes under voluntary participation — not measured or victimization crime — and the FBI cautions against using them to rank or compare places. See methodology §31.
