What the count covers

287 NPPES records list oncology pharmacist (1835X0200X) as their primary taxonomy with a practice address in California: 0.7 per 100,000 residents against 0.6 nationally (50 states and D.C.). San Francisco has 33 of them (11%).

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.
