About this ranking
Average number of 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. Counted where the job is located, from the reports employers file each quarter; monthly employment counts the jobs in the pay period that includes the 12th.
Counts jobs, not people: someone with two jobs counts twice. Covers about 95 percent of US wage and salary jobs. Excludes the self-employed, most agricultural workers on small farms, the armed forces, elected officials in most states, most railroad employees, some domestic workers and most student workers at schools. A count of employer reports, not a survey estimate like oews_employment.
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.
