ResearchContextual research literatureindicator reference

The peer-reviewed article studies changes in U.S. industry concentration since the late 1990s. It motivates longitudinal scrutiny of industry structure but supplies none of this indicator's 2022 Economic Census rows. Boundary: The paper's firm universe, measures, time window, and research design differ from the current Census industry-HHI contract. Its results are not joined to, pooled with, or used to validate these observations.

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.
