The PSC’s mission is to remain a national and world leader in research and training. Our goal is to link core research in the social and behavioral sciences to issues on the growth and structure of human populations and the role of socioeconomic stratification and human/social diversity in population heath. The PSC is characterized by continuity, innovative and high-quality population related research and maintains a flexible research infrastructure that enhances interaction, builds collaborations and encourages understanding of evolving issues. The Training program is a leader in the preparation and mentoring of Ph.D.’s and Post-Doctoral fellows and reflects a vision of the population sciences and health in which a strong background logic of demographic process is the gateway to an array of topics of public/scientific interest.
