The USC/UCLA Center on Biodemography and Population Health (CBPH) is one of 14 centers in the Demography and Economics of Aging Centers Program sponsored by the National Institute on Aging (NIA). The primary purpose of the CBPH is to provide a synergistic research environment for the integration and translation of research findings from a variety of disciplines to understand population health. This integration of biological, epidemiologic and medical risk information which characterizes Center research is fundamental to understanding and projecting demographic trends and differences in population health.
