What the count covers

10,224 NPPES records list speech-language pathologist (235Z00000X) as their primary taxonomy with a practice address in Illinois: 81 per 100,000 residents against 59 nationally (50 states and D.C.). Chicago has 1,753 of them (17%).

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.
