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
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.
Practice-location size
Share of Maryland providers at single- vs multi-provider practice locations, by normalized practice address. This is a proxy; see the limitations below.

Reading these numbers
Counts are NPPES registrations at Maryland 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.
