01 · TL;DR

Two categories moved in Humboldt Park this August, one a single-month below-trend signal and one a structural multi-month shift. The overall picture is mixed: violent crime categories are broadly down on a 12-month basis, while motor vehicle theft has been running well above prior-year levels for long enough to register as a sustained shift rather than a one-time move.

Arson is the month's most distinct signal, with only 7 incidents in the trailing 12 months against 12 in the year before, a 12-month count well below its recent historical range. Motor vehicle theft is pulling in the opposite direction: 550 incidents in the current 12 months against 422 in the prior year, a 30.3% rise that has now persisted long enough to reflect a structural change, not a noisy month. Everything else, including robbery down 24.3% and homicide down 60.0% on the 12-month comparison, fell within trend and generated no additional signals this period.

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.

Aggravated Assault

06 · Context & comps

How Humboldt Park compares

Peer neighborhoods picked by closest 12-month arson 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 arson 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.
