Kenwood sexual assault is the headline signal this month — a sharp above-baseline move that stands as the most statistically pronounced shift in Chicago's February 2025 briefing. Archer Heights other-larceny has been the recurring lead category, but that category's dominance across multiple neighborhoods this month is the backdrop, not the story: the fresh signal is in Kenwood.
Citywide volume is down 6.1% against the prior 12 months — 143,548 incidents against 152,882. The anomaly mix is heavily weighted toward zero-event and sustained-shift signals (77 and 66, respectively), but 23 spikes surfaced across 77 neighborhoods. Other-larceny accounts for several of those: Archer Heights, Beverly, and Hegewisch all registered spikes in the same category, pointing to a category-level pattern rather than isolated neighborhood noise.
The other-larceny thread across three neighborhoods is the month's structural story — one category appearing in three of the top five signals is a pattern worth tracking in March. The Kenwood sexual assault signal is newer and carries no multi-month streak to reference yet; February 2025 is its first appearance in the rankings.
Sustained drops worth naming
Motor Vehicle Theft ran below trend in the trailing 12 months — 26% down from the year before. Sustained shifts often precede a baseline reset; we surface them at the same prominence as spikes.
