What the count covers

181 NPPES records list contractor (171W00000X) as their primary taxonomy with a practice address in Illinois: 1.4 per 100,000 residents against 2.5 nationally (50 states and D.C.). Chicago has 35 of them (19%).

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.
