Chicago Crime Rate — January 2026

Hegewisch vandalism is the lead signal this month, registering the sharpest single-neighborhood move in the January 2026 briefing. No prior-month combo carries over as a recurring backdrop — this is a fresh signal with no inherited streak. The category and neighborhood combination had not been near the top of Chicago rankings in recent months.

Citywide volume is down 11.1% against the prior 12 months — 129,674 incidents against 145,945. The signal mix is broad: 90 sustained-shift signals and 77 zero-event signals dominate, with 12 fresh spikes spread across 77 neighborhoods. Armour Square sexual assault and Gage Park other-larceny both appear among the top fresh spikes, with other-larceny also registering in Archer Heights.

With 209 total signals and no recurring lead to anchor this briefing, January 2026 reads as a structurally active month rather than a continuation of a prior trend. The concentration of sustained-shift signals — 90 of 209 — suggests the citywide decline is broad-based and has been building across multiple categories, not driven by a single neighborhood or event.

Sustained drops worth naming

Homicide ran below trend in the trailing 12 months — 31% down from the year before. Sustained shifts often precede a baseline reset; we surface them at the same prominence as spikes.
