What the count covers

2,793 NPPES records list developmental therapist (222Q00000X) as their primary taxonomy with a practice address in Illinois: 22.3 per 100,000 residents against 5 nationally (50 states and D.C.). Chicago has 652 of them (23%).

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.
