After years of requests for American Hospital Association (AHA) data, the Medical and Marx libraries at Yale have made access to this important U.S. hospital data available for all Yale affiliates. Containing multiple decades of annual survey and supplemental datasets, this data resource provides information about U.S. hospitals' organizational structure, service lines, utilization, finances, insurance and payment models, and staffing, enabling peer comparisons, market analysis, and health services research.

To access AHA data, create an account on the platform, Wharton Research Data Services (WRDS), with your yale.edu email address. To learn more about how to get started, consult this research guide. If you already have a WRDS account, access AHA data now.
