What the count covers

942 NPPES records list genetic counselor (m.s.) (170300000X) as their primary taxonomy with a practice address in California: 2.4 per 100,000 residents against 2 nationally (50 states and D.C.). Los Angeles has 161 of them (17%).

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.
