Economy-wide observatory
U.S. industry concentration atlas
How concentrated each U.S. industry is, from broad sectors down to detailed lines of business, with each industry's sales, value of shipments, or revenue, and employment from the Census Bureau. Census categories are statistical groupings and are not necessarily antitrust markets.

NAICS hierarchy is an economic classification, not a legal product or geographic market definition.
Economy concentration plane
See scale and concentration together
Revenue uses a logarithmic axis, circle area follows employer-firm count, and color identifies the two-digit NAICS sector.

Compare the full NAICS hierarchy
HHI and concentration ratios are based on national sales, value of shipments, or revenue for employer firms.
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.
