What the count covers

171,666 NPPES records list behavior technician (106S00000X) as their primary taxonomy with a practice address in California: 441 per 100,000 residents against 173 nationally (50 states and D.C.). Monrovia has 16,526 of them (10%).

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.
