A record counts where a clinician lists a practice address, active or not, and may be an office that bills rather than where patients are seen. Raw counts track population, so the map shows records per resident instead.

Written with AI tools from the named public files; every figure is computed from those files (how it is made).

Reading the ranking

The count is where clinicians register a practice address. Telehealth clinicians licensed in several states are counted once, at the address on their record, and a large state can still have shortage areas: HRSA designates them county by county in its shortage area finder.

To check one clinician, find the NPI in the NPI lookup and confirm the license on the state board search.

Common questions

Which state has the most healthcare providers?

California, with 974,315 NPPES records at a practice address in the state, followed by New York with 545,291.

Which state has the most providers per resident?

Washington, D.C., with 6,827 records per 100,000 residents; Alabama has the fewest, 1,340. The 50 states and D.C. together have 2,176.

Does a record mean an active clinician?

Not always. A record counts where a clinician lists a practice address in NPPES, active or not, and the address can be an office that bills rather than where patients are seen. Verify any individual with the state board.
