About this ranking
Average number of establishments with jobs covered by unemployment insurance during the year, all industries, private and government, from the Quarterly Census of Employment and Wages (QCEW) of the U.S. Bureau of Labor Statistics. An establishment is a single place of business, such as a factory, store or office; a company with several locations has several.
Counts places of business, not firms: for firms use employer_firms. Changes in how large employers report their locations can move the count without any change in activity.
Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. 12 counties with data in other periods have no value for 2018 and are left out rather than filled from another source. Equal values share a rank.
