A Quasi-Experiment comparing the health of unhoused people who have and have not experienced an eviction in King County, WA
For policymakers and public health officials, this provides evidence that eviction exacerbates health risks for an already vulnerable unhoused population.
This study found that eviction is associated with an 8.3% increase in poor general health and a 9.5% increase in substance use disorder among unhoused individuals in King County, WA, but no significant effect on mental health.
Home eviction poses a significant threat to housing stability, a critical determinant of health. This study examines the relationship between eviction and health and substance use within the unhoused population of King County, Washington. Using a sample of 1,106 individuals experiencing homelessness, we employed a quasi-experimental design to compare the health outcomes of those who have experienced eviction with those who have not. Our findings reveal eviction is associated with an 8.3% point increase (SE = 0.039) in the likelihood of reporting poor general health and an 9.5% increase (SE = 0.032) in substance use disorder. No significant effect was found for mental health outcomes. While these results highlight the severe health risks linked to eviction, further research with more precise estimates is necessary to better understand long-term effects. These findings contribute to the growing evidence of how home eviction undermines the well-being of vulnerable populations.
