Martin Luther King, Jr. once said: “An individual has not started living until he can rise above the narrow confines of his individualistic concerns to the broader concerns of all humanity.”

That’s why we focus our attention on health disparities—that is, the significant differences seen in the health status of groups of people in the five-county area of Southeast Pennsylvania. A better understanding of those disparities and how they impact population health can help advance the effort to attain Dr. King’s vision of a broader sense of community and shared values.
