Auburn Gresham Crime Rate Trends — Chicago
Auburn Gresham is a South Side neighborhood organized around the 79th Street commercial corridor between Halsted and Western. Named for the Auburn Park subdivision and the village of Gresham that the city annexed in 1889; predominantly single-family bungalows.
Three signals shaped Auburn Gresham's August 2026 briefing: two one-month below-trend readings and one sustained structural shift. The mix is concentrated in violent crime, with aggravated assault and robbery accounting for all three moves, and the direction is uniformly downward.
Aggravated assault is the strongest single-month signal, with 368 incidents over the trailing 12 months against 427 in the prior year, a 13.8% reduction. Robbery shows the same pattern on both measures: a one-month below-trend reading and a sustained multi-month structural shift, with the 12-month total now at 107 compared to 205 the year before, a 47.8% decrease. Everything else in Auburn Gresham, burglary, vandalism, motor vehicle theft, and the remaining categories, came in within normal range this month.

All categories, last 24 months
Each panel: recent monthly count vs. trailing 12-month context. MoM is the most recent month vs. the one before; 12mo YoY compares the trailing year to the year before that.
What's been quietly true for a year
Spikes get attention. Sustained shifts shape policy. These are multi-quarter patterns where the past 12-month total differs meaningfully from the year before — they often precede the baseline resetting.
- Robbery has reset to a lower baseline.
The trailing 12-month count is 107, down 48% from 205 the year before. If the trend holds another quarter, it will pull the multi-year baseline down.
What next month likely looks like
Forecasts trained through August 2026, with a likely range we're 95% confident the actual count will fall inside. Categories with too little recent volume — or violent categories at the neighborhood level — show no forecast and are surfaced through signals above instead. See the methodology page for the gating rules.

How Auburn Gresham compares
Peer neighborhoods picked by closest 12-month aggravated assault 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 aggravated assault 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.
