What the count covers

129 NPPES records list preventive medicine/occupational environmental medicine physician (2083P0500X) as their primary taxonomy with a practice address in California: 0.3 per 100,000 residents against 0.3 nationally (50 states and D.C.). San Francisco has 19 of them (15%).

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.
