Consequences of the 2019 Public Charge Rule Announcement and Publication on Prenatal WIC Participation Among Immigrant Families: Evidence of Spillover Effects.

This study analyzed the effects of the announcement and publication of the 2019 Public Charge Rule on participation of the special supplemental nutrition program for women, infants, and children (WIC) among pregnant immigrants. A difference-in-differences approach was used to analyze the changes in prenatal WIC participation before and after the 2019 Public Charge Rule announcement and publication among immigrants relative to US natives. We identified 17,623,683 live singletons born in a hospital from 2015 to 2019.
