Residents under 18 outnumber those 65 and over, at 21.5 percent against 18.7 percent, a household formation profile rather than a retirement one.

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 $414,110 sits well above the median of $150,000, pulled up by a few larger deals, so the median is the better guide to what a typical borrower here gets. Only 8.7 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 Nassau County

Do SBA loans in Nassau County get paid back?

  • Loans with a final outcome recorded325
  • Paid in full254
  • Charged off71
  • Charge-off rate on resolved loans21.8 percent
  • Status: Charged off71
  • Status: Exempt from disclosure1,254
  • Status: Cancelled341
  • Status: Paid in full254
  • Status: Committed, not yet disbursed110

Of the 325 loans that have reached a final outcome, 21.8 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.

A further 29 of the county's 2,030 SBA 7(a) approvals are to borrowers in cities that match no Census place in Nassau County, the largest being North Baldwin (14), W Hempstead (3), Bellrose (1). Those are postal cities, unincorporated areas and cities outside the county, so no place row claims them; they are counted in the county total above.
