What the count covers

214 NPPES records list orthotist (222Z00000X) as their primary taxonomy with a practice address in California: 0.5 per 100,000 residents against 0.4 nationally (50 states and D.C.). San Francisco has 14 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.
