Exact relationship builder
Indicator comparison lab
Compare two measures while keeping their entities, periods, units, and source populations visible. A visual association does not establish causation.

Coverage diagnostics
What entered the plane, and what did not
Pairing coverage is reported separately for each indicator denominator. A matched row is not evidence that either source covers the full underlying economy.
A NAICS industry is a statistical classification, not a legally defined antitrust market. Use these national revenue concentration measures to screen where deeper product and geographic market analysis may be warranted, not to infer market power or liability. The relationship is descriptive and does not make a statistical industry equivalent to a legal antitrust market.
Quadrants use this filtered slice's medians: 405.8 and 31.0%.
Slice ledgers
Period and group structure
Counts and correlations stay inside exact paired rows. Small groups may be too thin for a stable descriptive association.

Reusable comparison packet
Carry the exact contract into analysis
The endpoint returns every matched row in the filtered slice, both observation identifiers, both source routes, evidence status, confidence, entity, group, and period.
This lab compares only declared same-entity, same-period pairs. Missing sides are excluded rather than imputed, correlation remains descriptive, and unlike universes are never combined into a composite market-power score.

15 declared planes, no arbitrary joins
Each route names both measures and its exact pairing rule. Select a plane to rebuild the lab around that bounded universe.
