Homelessness rate vs. rent in 67 large U.S. Continuums of Care, 2015-2025

HUD Point-in-Time homeless counts for 67 large urban Continuums of Care joined to Census rent and population data, with tests of how much rent levels and rent growth explain, and where Seattle/King County falls.

Coverage: 2015-2025 (PIT count years; no ACS 1-year data for 2020)

What this dataset measures

Large urban CoCs whose boundaries can be rebuilt from whole Census counties or places, so each homeless count can be matched to the population and rents of the same area. Built to test the common explanation that high housing costs account for Seattle/King County's homelessness.

King County total homelessness rate vs. rent-predicted rate, all large CoCs

Question: How far is King County's total homelessness rate per 10,000 above or below the rate predicted from its median rent, across 59-66 large CoCs?

  • Rent alone explains little of the variation across large CoCs, so the prediction intervals are wide.
  • King County switched to respondent-driven sampling in 2022; its 2022 and 2024 rates are not directly comparable with visual counts.
  • Cross-sectional association within one year; not a causal estimate.

Result: 2024 total, central method adjustment (1,100 people removed): 29.33 (95% PI -27.03 to 85.69); 2024 total, high method adjustment (3,600 people removed): 18.65 (95% PI -37.71 to 75); 2024 total, Major City sample, central adjustment: 9.54 (95% PI -52.44 to 71.51); 2024 total, Major City sample, high adjustment: -1.15 (95% PI -63.12 to 60.83)

Operation: Leave-one-out OLS of homelessness rate on median gross rent; King County residual with 95% prediction interval

Scope: 2024 fits, full sample and Major City sample

  • Rent alone explains little of the variation across large CoCs, so the prediction intervals are wide.
  • King County switched to respondent-driven sampling in 2022; its 2022 and 2024 rates are not directly comparable with visual counts.
  • Cross-sectional association within one year; not a causal estimate.

Robustness check for: King County total homelessness rate vs. rent-predicted rate, all large CoCs

Rent growth 2019-2024 vs. change in homelessness, large CoCs

Question: Did CoCs whose rents rose faster from 2019 to 2024 see larger increases in homelessness?

Result: Rent growth 2019-24 vs % change in total homelessness rate: r = -0.043 (95% CI -0.282 to 0.201); Rent growth 2019-24 vs % change in unsheltered rate: r = -0.007 (95% CI -0.249 to 0.235); Rent growth 2019-24 vs change in total rate per 10,000: r = -0.135 (95% CI -0.366 to 0.11)

Operation: Pearson correlation across CoCs, King County excluded

Scope: 66 large CoCs other than King County

  • ACS median gross rent includes long-tenure leases and lags asking rents.
  • Tests only whether changes in rent explain changes in homelessness; rent level remains the strongest cross-sectional correlate.
  • Several CoCs changed count methods between 2019 and their end year.

King County rank on rent growth and on change in homelessness, 2019 to latest full count

Question: Where does King County rank among 67 large CoCs on rent growth and on the increase in homelessness since 2019?

Result: Rent growth 2019-24: +21.5%, 60th of 67. Increase in unsheltered rate: +18.7 per 10,000, 4th of 67. Increase in total rate: +22.4 per 10,000, 7th of 67.

Operation: Rank of King County within the 67 CoCs

Scope: 67 large CoCs

  • As counted; the 2022 count-method change may account for 0 to about 3,600 of King County's 2024 count (central estimate about 1,100).
  • Descriptive ranks, not a causal estimate.

Limitations and reproducibility

Reproducible from public sources: Download the HUD workbook and ACS tables listed in sources, export the workbook sheets with xlsb-export-script, then run build-panel-script, peers-script and residuals-script (Node.js). Outputs match the tables here.

  • PIT counts are single January nights; methods vary by CoC and change over time.
  • King County changed its unsheltered count method in 2022 (respondent-driven sampling). The estimated effect ranges from 0 to about 3,600 people in 2024.
  • Rates per 10,000 are FactHub calculations. HUD does not publish CoC-level rates.
  • CoC boundaries are rebuilt from whole Census geographies with small gaps (see coc-geography).
  • Multi-county median rent is a renter-weighted average of county medians, not a true median.
  • Rent alone explains 2-14% of the variation in total rates across all 67 CoCs (24-45% among Major City CoCs).
  • All results are associations, not causal estimates.
