Reading the sole-proprietor share
For Adult Health Nurse Practitioner records, the 20.9% sole-proprietor share means that 6,474 active records are flagged that way in NPPES. The flag is a self-reported NPPES field and an imperfect proxy for private practice, so it may not fully reflect ownership, employment, or practice arrangements.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- An NPI record is not a direct measure of a clinician's current patient-care activity.
- The primary taxonomy is a classification choice and may not reflect every service or specialty a provider offers.
- Providers are counted once, by their primary taxonomy code only.
