Statewide totals

Active NPI records62,877
Registered sole proprietors9,828 (15.6%)

The sole-proprietor flag is self-reported, so 9,828 records and the 15.6% share should be read as reported registry classifications rather than a complete count of private practices. It is an imperfect proxy for private practice and may not capture every ownership or operating arrangement.
