Healthcare Access Tools

Calculators that turn federal HRSA shortage criteria and U.S. Census population data into answers for your own community.

According to the HRSA Data Warehouse, more than 8,000 primary-care Health Professional Shortage Area designations were in force as of June 2026, leaving roughly one in four Americans in a federally designated shortage area. See our methodology for the thresholds each tool uses.
