Each provider counts once under their primary taxonomy; the US share is printed beside each Connecticut figure for comparison.
When Connecticut'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.

Reading these numbers
Counts are NPPES registrations at Connecticutpractice 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.
