Objectives. To evaluate the effect of the Affordable Care Act (ACA) Medicaid expansions on national rates of home eviction and eviction initiation in the United States.

Methods. Using nationally representative administrative data from The Eviction Lab at Princeton University, we estimated the effects of the ACA Medicaid expansions on county-level evictions and filings from 2000 to 2016 with a difference-in-difference regression design.

Results. We found that Medicaid expansions were associated with an annual reduction in the rate of evictions by 1.15 per 1000 renter-occupied households (P < .001), a reduction of 1.59 eviction filings per 1000 renter-occupied households (P < .001), and a reduction in the average number of evictions by 46 (P < .05). We found additional evidence that increasing rates of African American residents in a county was associated with a greater rate of evictions filed, and increased rates of poverty and rent burdens relative to income were associated with more evictions both filed and completed.

Conclusions. Evictions decreased after Medicaid expansion, demonstrating further evidence of the substantive financial protections afforded by this coverage. The reduction in the eviction filing rate suggests that Medicaid expansion could be reducing evictions by preventing the court proceeding entirely.
