What this dataset measures
Built for a fact check of whether Seattle's 911 calls for trash and open fires are at a record. These are the three call types a 2021 news report said the fire department's encampment-fire count draws on (illegal burns, rubbish fires and encampment fires). January to October is used so 2026 can be compared with the same months of earlier years. The city's verified encampment-fire counts are included so readers can compare calls with fires confirmed at tents and RVs.

Limitations and reproducibility
Reproducible from public sources: Counted on November 9, 2026 with the city's Socrata API at https://data.seattle.gov/resource/kzjm-xkqj.json: $select=date_extract_y(datetime) as yr,type,count(*) as n, $where=datetime >= '2004-01-01T00:00:00' AND datetime < '2026-11-01T00:00:00' AND date_extract_m(datetime) <= 10 AND type in('Illegal Burn','Rubbish Fire','Encampment Fire'), $group=yr,type. Full years drop the month filter and end at 2026-01-01. Area counts add the latitude and longitude bounds given for each box. The city's verified encampment-fire counts were copied from the documents listed in each row (Figure 23 of each Human Services Department report).
- A dispatch call type is what crews were sent for, not the cause found on scene, so a call is not a confirmed fire or a confirmed encampment fire.
- Illegal burns include cooking, warming and backyard fires.
- The Encampment Fire call type began on August 6, 2021; before then such fires were dispatched under other types.
- Other outdoor fire types (brush, bark, dumpster) are not counted here.
- Area boxes are approximations of neighborhoods.
- The city's counts of verified encampment fires use the fire department's own judgment of which fires were at a tent or RV; they are a different measure from dispatch calls.
- The dispatch log can be revised; all counts were made on November 9, 2026.
