The Dartmouth Atlas Project provides a huge selection of regional or national atlases and reports. For more than 20 years, the Dartmouth Atlas Project has documented glaring variations in how medical resources are distributed and used in the United States. The project uses Medicare and Medicaid data to provide information and analysis about national, regional, and local markets, as well as hospitals and their affiliated physicians. They have displayed their information by separating each report by the title and a brief summary. Then they attach a pdf to access the full report of each one.
