Public Health or Welfare Agency: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, the sole-proprietor share indicates how many active records have that NPPES field marked, not how many agencies operate in private practice. The field is self-reported and is an imperfect proxy because it does not by itself establish ownership, employment arrangements, or whether an organization is publicly funded, nonprofit, or privately operated. Use the share as a descriptive indicator of NPPES reporting, not as a direct measure of the private-practice market.

By state

New NPI registrations by year

Counts reflect the year each NPI was first issued, among records still active today. The final year is partial: this data covers through 2026-01-11.

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.
• - These are active NPI records with this taxonomy as the primary classification, not necessarily distinct operating agencies or locations.
• - NUCC publishes no official definition for this taxonomy, so the classification alone does not describe each agency's services or legal structure.
• Providers are counted once, by their primary taxonomy code only.
