About this ranking

Sales, value of shipments or revenue of employer establishments in professional, scientific, and technical services (NAICS 54), in millions of current US dollars, from the U.S. Census Bureau Economic Census.

Economic Census, taken every five years: values exist for 2017 and 2022 only, and the 2027 census publishes about 2029. Revenue of employer establishments located in the place, in millions of current US dollars, not adjusted for inflation; nonemployers (nonemployer_receipts_usd_*) are not included, and government owned establishments are generally out of scope. Manufacturing is the value of shipments and wholesale and retail trade are sales, so an establishment selling to another counts in both and sectors do not add up to output or GDP. Cells that would disclose individual companies (flag D) or that Census does not publish are missing here, not zero; counties are published for 14 of the 18 sectors. Sectors follow NAICS 2017 for 2017 and NAICS 2022 for 2022.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. 4 counties with data in other periods have no value for 2022 and are left out rather than filled from another source. Equal values share a rank.
