About Us

The Population Studies Center (PSC) at the University of Pennsylvania (Penn) was founded in 1962 and stands as an international leader in research and training on the dynamic structure, organization, and health and well-being of human populations. The services that PSC provides have been funded by infrastructure grants awarded by the Population Dynamics Branch at Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) since 1978. The center and its associates are also supported by research grants and contracts awarded by federal agencies including the National Institutes of Health and the National Science Foundation and by private foundations. Penn’s School of Arts and Sciences is the administrative home of the PSC and provides generous dedicated support to the center.
