Region 3

Map of Region 3 States


Region 3, based in Philadelphia, serves Delaware, Maryland, Pennsylvania, Virginia, West Virginia, and the nation’s capital, Washington, D.C. The region is remarkable for its diversity. The Northeast Corridor and Interstate 95 link a stretch of urban cities, sprawling suburbs, and rural communities, forming the Mid-Atlantic portion of the Northeast megalopolis. The disparities in the health status of states within this region drive attention to a focus on health equity, bridging the urban-rural divide, and building regional partnerships.

Region 3 is the home of many world-renowned health institutions, distinguished universities, and robust local and state health-related organizations, which offers fortunate opportunities for partnerships and collaboration. Moving the needle to improve the health of Region 3 residents is the region’s primary goal. Through collaborative efforts with stakeholders, we have worked to increase vaccination rates, reduce maternal mortality, support those with substance use disorder, and assist with lowering the rates of heart disease, asthma, obesity, and HIV/AIDS.
