This map service displays healthcare resources supply in the United States. It shows the number of health care facilities (hospitals, medical centers, federally qualified health centers, and home health services) at the state, congressional district and county levels. The health care system capacity is calculated as the number of facilities in the area multiplied by the national average (number of people per facility). The number of facilities needed is calculated by dividing the area's population by the national average (number of people per facility). The facility surplus or need is calculated by subtracting the number of facilities needed (based on the population size) from the number of existing facilities. Accessibility and travel time are not considered in these calculations.The data was provided by the U.S. Department of Health Human Services and is current as of 2012. Other data sources include Health Data, and the U.S. Census Bureau.For feedback please contact: ArcGIScomNationalMaps@esri.com_______________________________Other Health Datapalooza focused content that may interest you: Health Datapalooza Health Datapalooza
