Overall Coverage Analyses

• The results corroborate findings from other data sources that insurance coverage increases were larger in states that expanded Medicaid. These estimates add to the existing literature because the treatment and control groups were more narrowly defined to exclude those previously eligible for Medicaid and those directly affected by other coverage expansions. By focusing on the group most likely to gain Medicaid eligibility (nondisabled low-income childless adults) and on states that implemented the Medicaid expansion in 2014, this study clarifies the important role played by increased Medicaid coverage in previously reported coverage gains.
• The authors found very little evidence of differential changes in private coverage between expansion and nonexpansion states. Estimates by insurance type yielded no significant evidence that the Medicaid expansion crowded out private coverage in the first year of the 2014 coverage expansion.
• While the authors found substantial increases in Medicaid coverage, take-up over the first year of the 2014 Medicaid expansion was limited relative to the size of the Medicaid-eligible uninsured population.

Subgroup Analyses

• Take-up was lower among men (compared with women), Hispanics and members of other racial/ethnic groups (compared with non-Hispanic whites and Blacks), and adults under age 36 (compared with older adults).
• Newly eligible adults in fair or poor health were more likely to gain Medicaid coverage than healthier adults.
• Heterogeneity across demographic groups in coverage gains and Medicaid take-up among nondisabled childless adults in poverty were often quite different from the patterns observed among all adults, with women and older adults more likely to gain Medicaid coverage than men and younger adults.
