Health Insurance Coverage Changes Under the Affordable Care Act Among High Housing Cost Households, 2010-18.

This study examines the impact of the Affordable Care Act (ACA) on health insurance coverage among rent-burdened households-those spending more than 30% of their income on rent-and non-rent-burdened households. Using data from American Community Survey, we find that Medicaid take-up rate increased 8.88 percentage points (pp) among rent-burdened households and 7.54 pp among non-rent-burdened households in expansion states. Conditional on household income and demographic characteristics, rent-burdened households exhibit a 1.5 pp higher likelihood of Medicaid enrollment, with an additional decline of 0.7 pp in employer-sponsored insurance and 1.0 pp in directly purchased insurance enrollment. These effects were more pronounced among individuals aged over 26 and those in states without state-run exchanges. The findings show the importance of tailored Medicaid policies to assist households facing housing burdens, especially for those ineligible for housing vouchers.
