What the count covers

17,815 NPPES records list clinical social worker (1041C0700X) as their primary taxonomy with a practice address in Massachusetts: 254 per 100,000 residents against 93 nationally (50 states and D.C.). Boston has 1,906 of them (11%).

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.
