Residents under 18 outnumber those 65 and over, at 20.5 percent against 16.6 percent, a household formation profile rather than a retirement one.

- Employment at those establishments193,461

- Establishments per 1,000 residents30.9
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 $566,672 sits well above the median of $262,200, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 14.8 percent of approvals run on real estate terms, so SBA credit here is mostly working capital and equipment rather than property acquisition.

SBA loan default and charge-off rates in Seminole County
Do SBA loans in Seminole County get paid back?
- Loans with a final outcome recorded95
- Paid in full86
- Charged off9
- Charge-off rate on resolved loans9.5 percent
- Status: Cancelled86
- Status: Charged off9
- Status: Paid in full86
- Status: Exempt from disclosure417
- Status: Committed, not yet disbursed38
Of the 95 loans that have reached a final outcome, 9.5 percent were charged off. This is computed only over resolved loans, because a loan still running has not yet succeeded or failed and counting it either way would be wrong.
Compare against the national and state SBA charge-off rates, computed the same way over resolved loans only.
