West of Twin Peaks Crime Rate Trends — San Francisco
West of Twin Peaks is a planned residential cluster — including Forest Hill, Miraloma Park, and Sherwood Forest — built largely between the 1910s and 1940s on the western slopes of the Twin Peaks ridge. It is defined by curving, leafy streets of single-family homes, with the wooded Mount Davidson at its southern edge.
Seven categories moved in West of Twin Peaks this June — four ran below trend in the current month and three reflect sustained structural shifts. The overall shape is broadly downward across property crime, with no spikes and no rare-event signals anywhere in the mix.
Vandalism is the sharpest single signal: the trailing 12-month total sits at 109 incidents against a baseline of 199, down 25.9% against the prior year. Theft from vehicle and motor vehicle theft both ran below trend as well — theft from vehicle at 117 incidents vs. 228 the year before, a 48.7% reduction. Robbery carries the deepest 12-month change in the bucket summary, down 63.6% to 16 incidents from 44 — though Other Larceny is the one category moving the other direction, up 20.0% to 264 incidents, and accounts for the lone countertrend in an otherwise downward month.

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.
- Theft from Vehicle has reset to a lower baseline.
The trailing 12-month count is 117, down 49% from 228 the year before. If the trend holds another quarter, it will pull the multi-year baseline down.
- Burglary has reset to a lower baseline.
The trailing 12-month count is 95, down 35% from 146 the year before. If the trend holds another quarter, it will pull the multi-year baseline down.
- Motor Vehicle Theft has reset to a lower baseline.
The trailing 12-month count is 69, down 34% from 105 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 June 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
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Arson
Below the volume threshold for a reliable forecast — too few incidents in recent months to project from.
Burglary
Homicide
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Motor Vehicle Theft
Other Larceny
Robbery
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Sexual Assault
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.

How West of Twin Peaks compares
Peer neighborhoods picked by closest 12-month vandalism 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 vandalism levels.”

How we built this page
Data → Anomalies → Forecast → Page
Incident data is pulled from SFPD's open dataset on DataSF, 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.
