These are counts of establishments physically operating in the county, not listings, so they are the supply side a feasibility study measures demand against. County Business Patterns counts private establishments with paid employees in March 2023, while the Quarterly Census of Employment and Wages above counts every unemployment-insured employer, public ones included, as a 2024 annual average, so the two establishment and employment counts differ.
