Download publicly available data from the Dartmouth Atlas Project!

Download publicly available data from The Dartmouth Atlas of Health Care. We offer access to decades worth of Medicare data, as well as supplemental materials including crosswalks and geographic boundary files. Most Atlas rates can be downloaded in several different ways – keep an eye out for these download options:

  • Longitudinal – these large files include multiple years of data to allow researchers to track measures over time
  • By Year – these files include all the measures in the category for a single year
  • Make Your Own Dataset – this feature allows you to choose one measure and then limit the years or geographic areas that are included in your dataset

Please note that the rates available on this site are also available in the Dartmouth Atlas dataverse with a persistent identifier (DOI), together with additional documentation and links to related publications. We strongly recommend that individuals who intend to use these rates for research download the rates from dataverse and use the dataverse DOI in any citations.
