South of Market Crime Rate Trends — San Francisco
South of Market — universally called SoMa — is the formerly industrial district south of Market Street, transformed since the 1990s into a dense mix of tech offices, condos, museums (including SFMOMA), and the convention space at Moscone Center. It carries a 24-hour rhythm distinct from the rest of the city, with nightlife clusters, the Caltrain terminus, and an uneven mix of long-time residents, single-room-occupancy hotels, and new-build towers.
South of Market logged six signals in June 2026 — three one-month below-trend drops and three sustained structural shifts, with no spikes and no rare events. The shape of the month is broadly downward across property crime, concentrated in categories that have been falling for the better part of a year.
Vandalism, burglary, and motor vehicle theft all ran below trend in the top three signals. Vandalism's 12-month total stands at 507, down 21.2% against the prior year and well below its multi-year baseline of 715. Burglary dropped 36.6% over the same window (256 vs. 404), and motor vehicle theft is down 31.7% (278 vs. 407) — both moving in the same direction as the sustained-shift signals, suggesting the decline is structural rather than a single quiet 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 340, down 41% from 576 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 256, down 37% from 404 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 278, down 32% from 407 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.

How South of Market 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.”
Tenderloin
473 incidents over the past 12 months — 34 below South of Market's 507.

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.
