What the count covers

38 NPPES records list clinical neuropsychologist (103G00000X) as their primary taxonomy with a practice address in Iowa: 1.2 per 100,000 residents against 1.6 nationally (50 states and D.C.). Iowa City has 16 of them (42%).

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.
