Source: NHIS 1963-1980. Low-income is family income less than $3,000 and moderate income between $5,000 and $10,000 (in real 1970 terms). All estimates are from separate regressions. Estimates are average marginal effects derived from logistic regression models. Models control for age (in dummies), race, gender, household head's age, household head's education, state fixed effects, year fixed effects, and state specific trends in the calendar year of survey. Medicaid is a 0/1 variable that equals 1 when Medicaid exists at the beginning of the 12 month hospital visit reference period. Standard errors (SE) are based on state clusters. All estimates are weighted.
