01 · TL;DR

Two signals surfaced in Auburn Gresham this month, both concentrated in a single category. Robbery registered a one-month below-trend signal and a sustained multi-year structural shift simultaneously, meaning the decline is not just a quiet September: the 12-month trajectory has moved well below where it ran in the prior period.

Robbery sits at 107 incidents over the trailing 12 months, down from 194 in the year before, a 44.8% reduction. That puts the current pace at roughly half the prior-year level. Every other tracked category, including aggravated assault (down 12.1% year-over-year), burglary (down 8.2%), and motor vehicle theft (down 3.3%), remained within normal range this month, with no fresh spikes or rare-event signals.

06 · Context & comps

How Auburn Gresham compares

Peer neighborhoods picked by closest 12-month robbery volume — a pragmatic v1 of peer matching. Demographic / housing-stock peer matching isn't built yet (we deliberately don't ingest income or race data alongside crime). Volume similarity has the right intuition: “neighborhoods experiencing comparable robbery levels.”

How we built this page

Data → Anomalies → Forecast → Page

Incident data is pulled from CPD's open dataset on the City of Chicago Open Data portal — IUCR-coded and mapped to 9 UCR-aligned categories (theft from vehicle isn't reliably separable in the public feed and rolls into other larceny). Aggregated to community area × category × month.Anomalies are surfaced using strict thresholds (~p < 0.01). Forecasts are Prophet with low-count gating; violent categories at the neighborhood level skip the forecast and show rare-event / streak signals instead.

Spike rule: 12-mo total > baseline mean + 2.5σ AND ≥ 20 incidents AND 6-mo confirms. Drop rule: 12-mo total < baseline mean − 2.5σ AND baseline mean ≥ 20. Rare event: any incident in the last 90 days, no prior comparable in ≥ 5 years.
