Notes: The sample consists of respondents to the 2010-17 ACS who are age 65 or older and income-eligible for Medicaid according to the criteria in their state of residence. In column (1), the sample is restricted to respondents who are enrolled in Medicare. In column (2), the sample includes respondents who are not enrolled in Medicare. The regressions include controls for black race, other race, Hispanic ethnicity, female, naturalized citizenship status, and education (high school diploma, some college, and college degree or more), age fixed effects, state fixed effects, and year fixed effects. Sample weights are used in model estimation. Standard errors clustered by state are reported in parentheses. Statistical significance is indicated by

^***for the .01 level,

^**for the .05 level and

^*for the .10 level.
