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.

The average approval of $463,721 sits well above the median of $246,100, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 25.0 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.
