What the count covers

833 NPPES records list registered nurse (163W00000X) as their primary taxonomy with a practice address in Iowa: 26 per 100,000 residents against 44 nationally (50 states and D.C.). Iowa City has 219 of them (26%).

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.
