What the count covers

4,528 NPPES records list peer specialist (175T00000X) as their primary taxonomy with a practice address in California: 11.6 per 100,000 residents against 9.5 nationally (50 states and D.C.). San Diego has 384 of them (8%).

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.
