Inner Sunset Crime Rate Trends — San Francisco
The Inner Sunset is a residential neighborhood south of Golden Gate Park, organized around the cafes and restaurants at the intersection of Ninth Avenue and Irving Street. Its character is shaped by proximity to UCSF's Parnassus campus, family households in single-family homes, and the cool, foggy western weather of the city.
Four categories moved in Inner Sunset this April — two ran below trend for the month and two reflect structural, multi-month declines. The shape is broadly downward across property crime, with theft from vehicle and vandalism the sharpest single-month signals and burglary showing a deeper, sustained shift that has been building over the trailing year.
Theft from vehicle stands out most: the current 12-month total is 94, down from 148 in the prior 12 months — a 36.5% year-over-year drop. Burglary is tracking similarly, 76 incidents against 116 the year before (-34.5%), and its sustained-shift signal means the decline isn't a single quiet month but a multi-year reset. Vandalism also ran below trend this month, with 70 incidents in the current 12 months versus 82 prior. The remaining tracked categories — robbery, aggravated assault, motor vehicle theft, and other larceny — all fell within range or showed their own year-over-year declines, reinforcing that the downward pressure in Inner Sunset is broad-based, not isolated to one category.
Notable signals 2

Vandalism

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.
- Theft from Vehicle has reset to a lower baseline.
The trailing 12-month count is 94, down 37% from 148 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 76, down 35% from 116 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 April 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 Inner Sunset compares
Peer neighborhoods picked by closest 12-month theft from vehicle 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 theft from vehicle 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.
