In 2018, the United Nations High Commissioner for Refugees estimated 70.8 million people could be considered forced migrants, which is nearly double their estimation just one decade ago. This includes internally displaced persons, refugees, asylum seekers, and stateless people. This drastic increase in forced migrants exacerbates the already urgent need for a systematic policy-related review of the available data and analyses on forced migration and refugee movements. 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.
