What the count covers

2,083 NPPES records list dermatology physician (207N00000X) as their primary taxonomy with a practice address in California: 5.3 per 100,000 residents against 4.7 nationally (50 states and D.C.). San Diego has 152 of them (7%).

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.
