Crime Rate in Downers Grove, IL (2025)

Downers Grove has a Crime Index of 90 out of 100 (grade A — very safe) for 2025, based on FBI-reported violent and property crime rates relative to other US cities. That ranks it #8 of 29 cities in Illinois by reported crime. Reported crime is not the same as actual crime. Research on the gap between crime that occurs and crime that gets reported to police — often called the "dark figure" of crime — estimates that roughly 40% of violent crime and about a third of property crime go unreported each year. Every index built on official statistics, including this one, necessarily undercounts real crime. That gap is exactly why homicide — the offense with the smallest dark figure — anchors the calculation instead of a more commonly reported but less reliable category like theft.

A "Very safe" grade means Downers Grove's severity-weighted crime rate falls in the 88–100 range on the Crime Index, out of a national distribution of every city we track for 2025. Grades are calibrated against the national distribution of every area we track for the same data year — they describe an area's relative standing, not an absolute promise. A "Very safe" grade means an area sits among the lowest-crime places in the country with usable data, not that nothing ever happens there.

No. National research on the dark figure of crime estimates that roughly 40% of violent crime and about a third of property crime are never reported to police, so any index built on official statistics — including this one — measures a floor on real crime, not a ceiling. That's part of why the index leans most heavily on homicide, the category with the smallest reporting gap.
