Providers per 100,000 by county

Providers are allocated to counties from their practice ZIP code. We withhold the rate for one county (Brown), where a single practice address holds at least half the providers registered there — typically a regional employer that enrols its whole clinical staff at one headquarters, which inflates that county and thins its neighbours. The same values appear in the table.

When Ohio's providers entered the registry

Active providers by NPI registry-entry year. Registry entry is not licensure. Clinicians typically register when they start billing, so this measures registrations, not the workforce itself. 2026 is a partial year.

Reading these numbers

Counts are NPPES registrations at Ohio practice addresses. They are headcounts, not FTEs or license tallies. Telehealth and multi-state practice are invisible; taxonomy self-designation is not license verification; the registry lags moves and retirements. Details: methodology.
