What the count covers

705 NPPES records list contractor (171W00000X) as their primary taxonomy with a practice address in Ohio: 6 per 100,000 residents against 2.5 nationally (50 states and D.C.). Columbus has 76 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.
