Tenderloin Crime Rate Trends — San Francisco
The Tenderloin is a dense, downtown neighborhood west of Union Square, historically home to single-room-occupancy hotels and a long-running concentration of poverty, homelessness, and street drug markets. It also carries a cultural legacy of jazz, theater, and LGBTQ+ history that predates much of the rest of the city's downtown — including the Little Saigon stretch along Larkin Street.
August 2026 produced a single notable signal in the Tenderloin: a below-trend reading for robbery. Every other tracked category came in within its normal range, making this a structurally calm month against what has been a broadly declining backdrop across property and violent crime.
Robbery is the one category that moved, and it moved in the same direction as the 12-month trend: 239 incidents in the current trailing year against 292 in the prior 12 months, down 18.2%. Theft from vehicle and motor vehicle theft are also running well below prior-year levels, down 17.2% and 13.2% respectively, reinforcing a pattern of sustained property crime reduction. Sexual assault is the one category running above its prior-year pace, 17 incidents against 9, though volumes remain low and no single-month signal surfaced for that category this briefing.
Notable signals 1
Robbery
The past 12 months saw 239 incidents — about 33% below the 358 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.
No sustained shifts surfaced this month.
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
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.
Theft from Vehicle
Vandalism
How Tenderloin compares
Peer neighborhoods picked by closest 12-month robbery 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 robbery levels.”
South of Market
221 incidents over the past 12 months — 18 below Tenderloin's 239.

270 incidents over the past 12 months — 31 above Tenderloin's 239.

Top terms in incident descriptions for Tenderloin, excluding generic crime taxonomy. Useful as texture — what kinds of specifics show up here that don't show up elsewhere.
Hour-of-day, day-of-week, and seasonality
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.
