Note. Cases were weighted by NHIS final survey weights. Before and after were defined based on specific month to each state based on expansion date in the expansion states, and in non-expansion states before and after were defined using Jan 2014 as a cutoff. Unadjusted DID were the changes in racial/ethnic disparities in expansion states after expansion, compared to those in non-expansion expansion states. Adjusted DID were estimated using stratified regressions by each race/ethnicity and seemingly unrelated estimation, controlling for unemployment rate, state-fixed effects, and quarter/year-fixed effects and the health care need index.
