Capitol Hill Crime Rate Trends — Seattle
Capitol Hill is a dense neighborhood on the ridge east of downtown, anchored by Broadway, Pike/Pine, and Cal Anderson Park. The center of Seattle's nightlife and arts scene, with Volunteer Park, the Capitol Hill light rail station, and Seattle Central College as anchors.
September 2026 was a structurally quiet month for Capitol Hill, with no tracked category generating a notable single-month move. The one signal across the neighborhood was a zero-event on homicide, meaning the category produced no incidents in the current period. The broader picture is a broad, multi-category decline in property crime over the trailing 12 months.
Vandalism is down 20.6% against the prior year, 482 incidents vs 607. Motor vehicle theft fell 15.2%, from 494 to 419. Other larceny dropped 13.3%, robbery 12.6%, and burglary 8.7%. Arson ran the other direction, 14 incidents in the current 12 months against 9 in the prior year, a 55.6% rise on low absolute volume. Aggravated assault edged 5.3% above the prior year. Everything else was within a modest range or declining, and no category crossed a single-month anomaly threshold this briefing.
Notable signals 0
Nothing notable surfaced this month — every category sits within normal range against its baseline.
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 September 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.
Theft from Vehicle
Vandalism
How Capitol Hill compares
Peer neighborhoods picked by closest 12-month homicide 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 homicide levels.”
Recurring local terms (last 12 months)
Top terms in incident descriptions for Capitol Hill, 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 SPD's Crime Data feed on Seattle Open Data, 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.
