Question, mandate, boundary, and evidence need

Public question

Which detailed industries account for broad-sector concentration patterns, and where does strict historical evidence show structural movement?

Institutional mandate

Keep Census industry distributions, strict same-code history, business flows, and reviewed market context inspectable at their published levels.

Interpretation boundary

A NAICS industry is a statistical classification, not automatically an antitrust market. Sector medians, revenue concentration, and business dynamics retain different units and vintages.

Evidence still needed

Strict six-digit histories, disclosure status, firm and establishment context, product and geographic boundaries, entry, conduct, prices, quality, and enforcement records.

Primary audienceIndustrial-organization researchers, sector analysts, and public agencies
