To explore the causes and impacts of forced migration and population displacement, the National Academies convened a two-day workshop on May 21-22, 2019. The workshop discussed new approaches in social demographic theory, methodology, data collection and analysis, and practice as well as applications to the community of researchers and practitioners who are concerned with better understanding and assisting forced migrant populations. This workshop brought together stakeholders and experts in demography, public health, and policy analysis to review and address some of the domestic implications of international migration and refugee flows for the United States. This publication summarizes the presentations and discussions from the workshop.
