Results are effects of the ACA on the proportion of residents with the specified type of insurance, evaluated at the mean pretreatment uninsured rate. Standard errors, heteroskedasticity‐robust and clustered by state, are in parentheses. *** indicates statistical significance at 0.1% level, ** at 1% level, and * at 5% level. Sampling weights are used. All regressions include area and time fixed effects and the full set of controls.
