What the count covers

1,082 NPPES records list registered respiratory therapist (227900000X) as their primary taxonomy with a practice address in California: 2.8 per 100,000 residents against 1.3 nationally (50 states and D.C.). Los Angeles has 200 of them (18%).

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.
