01 · TL;DR

March 2026 brought four signals across Montclare — two spikes, one streak break, and one sustained shift. The headline is upward pressure across multiple categories, not a single outlier: other larceny and aggravated assault both spiked in the same month, while a homicide streak break added a structurally different kind of signal to the mix.

Other larceny is the largest mover by volume: 200 incidents in the current 12-month window against 120 in the prior year, a 66.7% rise. Aggravated assault is up 57.9% over the same period — 30 incidents vs. 19. The homicide streak break is a separate signal type: a category surfacing after a quiet gap, distinct from the volume-driven spikes. Burglary ran the other direction, down 40.0% year-over-year, and robbery fell 20.0% — the two categories pulling against the otherwise upward month.

05 · Forecast

What next month likely looks like

Forecasts trained through March 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

NO FORECAST

Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.

Arson

NO FORECAST

Below the volume threshold for a reliable forecast — too few incidents in recent months to project from.

06 · Context & comps

How Montclare compares

Peer neighborhoods picked by closest 12-month other larceny 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 other larceny 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.
