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.

Provider-type mix vs the national picture
Each provider counts once under their primary taxonomy; the US share is printed beside each Ohio figure for comparison.
When Ohio's providers entered the registry
This chart shows active providers by the year they entered the NPI registry. 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.
Practice-location size
This shows the share of Ohioproviders at single- and multi-provider practice locations, grouped by normalized practice address. It's only a proxy, so see the limitations below.

Reading these numbers
Counts are NPPES registrations at Ohiopractice addresses. They are headcounts, not FTEs or license tallies. Telehealth and multi-state practice don't show up, a self-designated taxonomy isn't license verification, and the registry lags behind moves and retirements. The methodology page has the details.
