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.
