Our Data Host: The Health and Medical Care Archive

The Health and Medical Care Archive (HMCA) at the University of Michigan's Inter-University Consortium for Political and Social Research is the official data archive of the Robert Wood Johnson Foundation. HMCA is devoted to preserving and making available research data to expand knowledge about and contribute to the improvement of the health and health care of all Americans.

HMCA data are free and immediately accessible to all researchers, students and policy-makers. Each one of more than 100 collections includes complete documentation, often including original survey questionnaires; links to related publications; and access to restricted data.

Data collections in HMCA are organized under five categories:

  1. Health Care Providers
  2. Cost/Access to Health Care
