01 · TL;DR

Three signals moved in Bronx CD12 — Williamsbridge / Baychester this month: one single-month spike and two sustained shifts, both pointing upward. The shape is concentrated rather than broad — this isn't a neighborhood where every category shifted, but where the categories that did move are doing so with structural weight.

Sexual Assault is carrying both signals: a one-month spike and a multi-month sustained shift, with the current 12-month total at 321 incidents against a prior-year total of 239 — up 34.3%. Theft from Vehicle is the second sustained shift, up 36.6% over the prior 12 months (332 vs. 243). Every other tracked category — including Robbery, down 13.5%, and Arson, down 60.0% — ran within range or below trend.

06 · Context & comps

How Bronx CD12 — Williamsbridge / Baychester compares

Peer neighborhoods picked by closest 12-month sexual 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 sexual assault levels.”

How we built this page

Data → Anomalies → Forecast → Page

Incident data is pulled from SFPD's open dataset, mapped to 10 NIBRS-aligned categories, and aggregated to neighborhood × 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.
