Yasenov VI, et al. - In this difference-in-differences analysis of data on 208,060 immigrants from the American Community Survey from 2000 through 2016, experts investigated whether expansion of public health insurance to non–US-born, lawful permanent resident children and pregnant women during their first 5 years of residency was related to raised interstate migration among these groups. Results imply that states recognizing expanding healthcare benefits coverage to freshly arrived immigrant children and pregnant women could be unpromising to experience in-migration of these persons from other states, which, in turn, has significant indications for understanding short- and long-term program costs.
