Professor Hamilton Studies Disparities Around Birth & Medicaid

School of Public Policy (SPP) Professor Christal Hamilton joined the SPP Network in August after previously serving as a postdoctoral research scientist in the Center on Poverty and Social Policy at Columbia University. In 2023 she was published in the Population Research and Policy Review and Duke University Press.

Christal HamiltonIn July, she co-authored “Medicaid Health Insurance Coverage Among the Foreign-Born Following ACA Implementation: Disparities by Migration Status” with Professor Claire E. Altman (University of Minnesota), Professor James D. Bachmeier (Temple University) and Dr. Cody Spence (U.S. Census Bureau). With the Population Research and Policy Review they estimated the impact of the Affordable Care Act’s Medicaid expansion on health coverage in foreign-born populations. They found that disparities persist across migration status of groups, especially for the unauthorized, and they have implications on health and immigration policy reform.

Before joining SPP in August, she co-authored “Experiences of Poverty Around the Time of a Birth: A Research Note” with Professor Laurel Sariscsany (University of Nebraska Omaha), Professor Jane Waldfogel (Columbia Unviersity) and Senior Research Scientist and Co-Director Christopher Wimer (Columbia University – Population Research Center and Center on Poverty and Social Policy). Their note utilized data from the Survey of Income and Program Participation and the Supplemental Poverty Measure. They examined “…the poverty rate of mothers overall and by birth parity and racial and ethnic group in the six months before and after childbirth (Duke University Press). The team found a need for increased public assistance for mothers with recent births, and calls attention to a policy need to address racial and ethnic disparities.
