Archer Heights other larceny is the lead signal this month, registering the largest single-neighborhood move in the top-five rankings. Hegewisch vandalism was the prior lead — but the vandalism category itself has now appeared at the top of the rankings for a stretch, so the editorial focus shifts to the fresh bucket. The Archer Heights other-larceny spike is the most novel move in November 2025.
Citywide volume is down 11.5% against the prior 12 months — 131,580 incidents against 148,705. The signal mix across 77 neighborhoods is active: 12 fresh spikes against 16 below-trend signals, with 100 sustained-shift signals forming the structural backdrop. Logan Square sexual assault and East Side motor vehicle theft both appear in the top five alongside the two other-larceny moves, suggesting the spike activity this month is spread across categories rather than concentrated in one.
The 100 sustained-shift signals are the dominant feature of the longer arc — that count has been the bulk of the anomaly mix for months, and the 11.5% year-over-year decline holds at a meaningful level. The fresh spikes in November are worth tracking into December, but with 77 zero-event signals also in the mix, the structural downward trend across Chicago remains the primary story.
Sustained drops worth naming
Robbery ran below trend in the trailing 12 months — 35% down from the year before. Sustained shifts often precede a baseline reset; we surface them at the same prominence as spikes.
