What this dataset measures

Health Through Housing is the county's sales-tax program that turned hotels and apartment buildings into homes for chronically homeless people, and its dashboard and annual report are where its own plan says results are reported. The other agencies and operators are where results for the same people could also appear.

Change in Health Through Housing residents' use two years after move-in

Question: What results does Health Through Housing publish about residents' health and safety, and which are missing?

Operation: Rows of the two-year change table as printed; unpublished measures carried as null

Scope: All Health Through Housing residents, second year after enrollment compared with the 12 months before, 2025 reporting

  • Before-and-after change with no comparison group; people often move in after a crisis year, so some decline would be expected anyway.
  • The county does not say how residents who died are counted; a resident who dies has no later visits.

Limitations and reproducibility

Reproducible from public sources: Each published figure is printed in the 2025 annual report or the dashboard's data table appendix at the page or table given. 'Not published' means the measure appears nowhere in the 2025 dashboard (all tabs), the 18-page data table appendix or the 2022 to 2025 annual reports, including their endnotes, which we read in full and also searched for overdose, death, deceased, died, passed away, sobriety, abstinence, substance use and treatment.

  • Not published means not in public reports. The county may track drug use, overdoses or deaths internally; the Medicaid claims and Medical Examiner records it already uses could show them.
  • The emergency room, hospital and jail changes compare residents' use in the year before move-in with use one or two years after. There is no comparison group, so the figures show change, not what housing caused.
  • The county's in-depth evaluation of the program is due by December 31, 2026 and was not published when we checked; it may add measures.
  • Public Health - Seattle & King County separately counts fatal overdoses among everyone living in permanent supportive housing countywide; those counts are not broken out for Health Through Housing.
  • Deaths appear only as a one-line count in the annual reports (15 residents who died while enrolled in 2024, 10 in 2025), placed in the discussion of emergency housing exits, with no cause, site or rate; it is unclear whether the count covers supportive housing residents.
  • The hospital and ER changes cover only residents who agreed to share their identifying information in the county's homeless records (2025 annual report, endnote 55).
  • Other places were checked by reading their latest public reports; the regional homelessness authority's interactive dashboard and Seattle's Human Services Department were not checked.
