Key Analytical Findings

Insights from sampling 3,000 records per resource type across the full 27.2M dataset

Nurse Practitioners Lead

NPs are the #1 specialty in PractitionerRole records (8.8%), surpassing Family Practice and Internal Medicine — reflecting the national shift toward advanced practice providers.

Florida Dominates Organizations

FL accounts for a disproportionate share of organizations in the sample (2,058 vs. CA's 1,078), likely driven by large Medicare Advantage enrollment and health plan network reporting.

100% NPI Coverage

Every Practitioner and Organization record carries a valid NPI identifier, making this the most comprehensive NPI-linked dataset available in the public domain.

5M FHIR Endpoints

The Endpoint resource contains 5.0M FHIR API URLs — all HTTPS, all active — representing the interoperability backbone of US healthcare, mandated by the 21st Century Cures Act.

GPS Coverage Gap

Only 46.6% of Location records include GPS coordinates, revealing a significant opportunity for geocoding enrichment to enable proximity-based provider search.

Gender Skew in Sample

66.3% of Practitioners in the sample are female — driven by the high representation of nursing, social work, and behavioral health roles which are female-dominated professions.
