Statewide totals
| Active NPI records | 148,227 |
| Registered sole proprietors | 25,942 (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.
