What the count covers

102 NPPES records list allergy & immunology physician (207K00000X) as their primary taxonomy with a practice address in Colorado: 1.7 per 100,000 residents against 1.2 nationally (50 states and D.C.). Denver has 29 of them (28%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
