Look up a state or county to see its federal healthcare-shortage status. According to the Health Resources and Services Administration (HRSA) Data Warehouse, more than 8,000 primary-care Health Professional Shortage Areas were active as of June 2026, spread across 3,291 counties. Every figure on this site is rendered directly from that federal data; if you are not sure where to start, the guides explain how HPSA and Medically Underserved Area designations work, and the methodology documents how each number is computed.
