What the count covers

3,542 NPPES records list doula (374J00000X) as their primary taxonomy with a practice address in California: 9.1 per 100,000 residents against 5.5 nationally (50 states and D.C.). Los Angeles has 232 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.
