The Office of Population Research (OPR) at Princeton University, founded in 1936, is one of the nation’s oldest demographic research and training centers. OPR has a distinguished history of contributions in formal demography and the study of fertility change. Subsequent generations of OPR scholars have made significant and ground-breaking contributions in the areas of social demography, bio-social interactions, health and wellbeing, children, youth and families, poverty and racial/ethnic inequality, urbanization, migration and development, and innovative methodologies.
