Cross-system interpretation boundary

This bridge links reviewed broad industry-category codes for navigation across two separate statistical systems. It does not assert that OECD enforcement classifications and Census sectors are identical, that either is a relevant antitrust market, or that their measures share a denominator. OECD rows count classified infringement decisions in 2021-2024; Census rows summarize six-digit industry distributions in 2017 and 2022 and sector business flows in 2023. Positions, ranks, gaps, and co-movement must not be read as market concentration, enforcement responsiveness, competitive harm, deterrence, liability, or causation.

Each OECD category is assigned through an explicit reviewed broad-sector code table. No fuzzy text matching is used. Seventeen codes join to the current Census sector-economy packet; Agriculture (11), Management of companies and enterprises (55), and Public administration (92) retain their classification links but disclose that the joined Census evidence packet is unavailable.

Classification and interpretation boundary

One reviewed navigation layer, four separate evidence releases.

The broad-sector code is the bridge, not a shared metric. Enforcement counts remain OECD activity observations. Census structure remains a distribution across published six-digit industries; strict history and business flows retain their own cohorts and years. The bridge supports source inspection and question formation, not inference across systems.
