The top panel of the table estimates the impact of the state policies on the relative
change in Medicaid enrollment. In the full-interaction specification, the triple-difference
coefficient for non-citizens is −0.049 (with a standard error of −0.025) in the sample of all
persons, and −0.105 (0.048) in the children’s sample. The state policies, therefore, had a
significant impact on Medicaid participation in the non-citizen population. In other words,
non-citizens residing in states that did not offer state-funded assistance programs to their
immigrant populations experienced a significant decline in their Medicaid participation
rates, and the decline was particularly steep for non-citizen children. In contrast, these
programs did not affect the relative Medicaid participation rate of citizens or of the children
of citizens
