The Population Research Institute (PRI) is a multidisciplinary center that supports innovative population research. Now with 94 PSU and 35 non-PSU faculty researchers, PRI was established over four decades ago and funded by the National Institutes of Health since 1992. PRI’s overarching aim is to advance the scientific understanding of human population dynamics and processes, especially as they relate to PRI’s primary research areas: Communities, Neighborhoods and Spatial Processes; Immigration, Migration and Immigrant Integration; Families, Networks and Social Change; Population Health; and Environment and Health.
