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. Equal values share a rank.
