Individual health-insurance concentration using KFF's 2024 source-reported national and state measures for the ACA-regulated individual market. The profile anchors the national HHI and links to 51 separately reported state and District of Columbia screens without extending the evidence to employer insurance, Medicare, Medicaid, or every insurance product.

Graph contract

Relationship families stay separate

The atlas joins routes through encoded custody and context, never through name resemblance or an inferred corporate, legal, or causal relationship.

The atlas exposes only relationships declared in the current public data. A link or issue grouping does not make unlike measures comparable, establish ownership or control, define an antitrust market, assign liability, or show that a policy event caused an economic outcome.

Reusable graph packet

Carry node and edge custody into analysis

The packet preserves node type, canonical route, relationship family, source link, evidence label, confidence, and edge-specific guardrail.
