OVERALL COMPONENT: PROJECT SUMMARY The Population Studies and Training Center (PSTC) promotes innovative research on social, institutional, and environmental dimensions of population structures and processes fundamental to health and well-being. Established in 1964, the PSTC benefits from a deep, interdisciplinary network of committed scholars at Brown. This application describes how a new round of dedicated resources for this dynamic community of 62 faculty associates will advance knowledge within and across social science and public health fields, and leverage significant university investment for research activity. The PSTC will make distinctive intellectual contributions in each of five Primary Research Areas: Migration and Urbanization; Children, Families, and Health; Reproductive Health and HIV/AIDS; Population, Development, and Environment; and Social Foundations of Health Disparities.
