Eviction rates in California before and after Medicaid expansion

Early Medicaid expansion in California was associated with a reduction in the number of evictions, with 24.5 fewer evictions per month in each county from a pre-expansion average of 224.7. These results imply that for every thousand new Medicaid enrollees in California, Medicaid expansion was associated with roughly twenty-two fewer evictions per year. Additionally, there was a 2.9% reduction in evictions per capita associated with early expansion.
