The PSC’s mission is to remain a national and world leader in research and training 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.
