What the count covers

27,741 NPPES records list addiction (substance use disorder) counselor (101YA0400X) as their primary taxonomy with a practice address in California: 71 per 100,000 residents against 28 nationally (50 states and D.C.). Los Angeles has 2,101 of them (8%).

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.
