Statewide totals

Active NPI records144,497
Registered sole proprietors35,261 (24.4%)

The 24.4% figure describes the share of these records flagged as sole proprietors in NPPES, not a definitive measure of private practice. Because the flag is self-reported and an imperfect proxy, it should be read as an administrative indicator and considered alongside other workforce information.
