Comparable here

National six-digit rows sharing the employer-firm universe and revenue-based concentration basis; signed changes require an identical code, level, sector, and label in both Census tables.

Still requires judgment

A relative rank is a screening signal. Product and geographic market definition, competitive effects, entry, and legal conclusions require separate evidence.

Selection console

Choose two to four detailed industries

Every rank and percentile uses the same 899 six-digit NAICS rows, so hierarchy level stays fixed across the comparison.

NAICS industries are national statistical screening categories, not legally defined antitrust markets. Cross-sector comparisons describe relative Census position; they do not establish product substitutability, geographic scope, market power, or liability.
