What the count covers

40 NPPES records list neonatal-perinatal medicine physician (2080N0001X) as their primary taxonomy with a practice address in Delaware: 3.9 per 100,000 residents against 2.3 nationally (50 states and D.C.). Newark has 20 of them (50%).

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.
