Published 'stay housed' rates for King County supportive housing

What this dataset measures

These are the 'stay housed' figures officials and operators quote for the county's homeless housing, from the regional authority (federal measure, quarterly report, dashboard), the county's Health Through Housing program, and the two largest operators, DESC and Plymouth. The death counts are the only public counts of deaths among supportive housing residents we found.

Limitations and reproducibility

Reproducible from public sources: Each rate and count is printed in the source named on its row. The scenarios add the death counts to the rate's base: rate = people counted as staying or moving to permanent housing / (people in the rate's base + deaths added).

• The scenarios are illustrations of scale, not corrected rates. The federal rate counts people in permanent housing projects that report to the county's homeless records (October 2022 to September 2023); the death counts come from Medical Examiner records for other periods and a wider or narrower set of buildings.
• The 225 overdose deaths are for calendar 2024, not the rate's October 2022 to September 2023 year. Overdose deaths at housing sites were higher in 2023 (281) than in 2024 (235) in the county's fatal overdose dashboard, which uses the Medical Examiner's broader housing category, so the 2024 count is not likely to overstate.
• Overdose deaths leave out other causes. The 487 all-cause deaths include income-restricted and recovery housing as well as supportive housing, and only deaths the Medical Examiner investigates; natural deaths under a doctor's care are mostly missing.
• Some residents who died may already be outside the federal rate's base for other reasons (no move-in date, a building not in the records), and some deaths may be of people not in the rate at all.
• For rates marked Not stated, the publisher does not say how deaths are handled; we could not confirm whether they are left out, counted as not staying housed, or counted as staying housed.
• Health Through Housing's death counts appear in its discussion of emergency housing exits; it is unclear whether they cover supportive housing residents.
