Hayes Valley Crime Rate Trends — San Francisco
Hayes Valley is a walkable residential and commercial neighborhood west of City Hall, transformed since the 1989 Loma Prieta earthquake demolished the Central Freeway that once divided it. Today it is known for its boutiques, design-forward restaurants, art galleries, and the central green space of Patricia's Green amid Victorian and Edwardian architecture.
Three categories moved in Hayes Valley this August: one one-month below-trend signal and two structural shifts that have been building across the trailing 12 months. The dominant story is divergence, property crime pulling in opposite directions depending on category.
Vandalism is the strongest single signal, down to 157 incidents over the current 12 months against 186 the year before, a 15.6% decline. Theft from vehicle has compressed even more sharply, 169 incidents versus 290 in the prior 12 months, a 41.7% reduction that reads as a structural change, not a one-month dip. Running the other way, other larceny has climbed to 393 over the same window against 307 before, up 28.0%, and that sustained increase is the counterweight to the declines elsewhere. Everything else, robbery, aggravated assault, burglary, motor vehicle theft, stayed within normal range.
Notable signals 1
Vandalism
The past 12 months saw 157 incidents — about 44% below the 282 average from prior years.
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 169, down 42% from 290 the year before. If the trend holds another quarter, it will pull the multi-year baseline down.
- Other Larceny is climbing.
The trailing 12-month count is 393, up 28% from 307 the year before. If the trend holds another quarter, it will pull the multi-year baseline up.
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
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.

Vandalism
How Hayes Valley 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.”

Distribution of bucketed incidents in this neighborhood across the full analysis window. Useful for routine context — shopping-strip thefts vs. late-night assaults read very differently when you can see when each typically happens.
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.
