Provider-type mix vs the national picture
Each provider counts once under their primary taxonomy; the US share is printed beside each Maryland figure for comparison.
When Maryland'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 Marylandproviders 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 Marylandpractice 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.
