How does the Dartmouth Atlas Project get access to its data? Where does the data come from?
The very large claims databases used in the DAP come from the Centers for Medicare and Medicaid Services (CMS), the federal agency that collects data for every person and provider using Medicare health insurance. Access to this data is made available for research purposes. Other data sources include U.S. Census, the American Hospital Association, American Medical Association, National Center for Health Statistics, and Claritas, Incorporated.
