Statewide totals

Active NPI records148,227
Registered sole proprietors25,942 (17.5%)

The 17.5% figure indicates the share of these records flagged as sole proprietors, not a direct measure of private-practice participation. The flag is self-reported and is an imperfect proxy for private practice, so it should be interpreted as a registry characteristic rather than a definitive workforce classification.
