What the count covers

1,874 NPPES records list dental hygienist (124Q00000X) as their primary taxonomy with a practice address in California: 4.8 per 100,000 residents against 4.7 nationally (50 states and D.C.). San Diego has 110 of them (6%).

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.
