The average approval of $500,155 sits well above the median of $200,000, so a small number of large deals is pulling the mean up. The median is the better guide to what a typical borrower here actually gets. Only 12.6 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 Middlesex County
Do SBA loans in Middlesex County get paid back?
- Loans with a final outcome recorded177
- Paid in full151
- Charged off26
- Charge off rate on resolved loans14.7 percent
- Status: Paid in full151
- Status: Exempt from disclosure710
- Status: Cancelled186
- Status: Charged off26
- Status: Committed, not yet disbursed70
Of the 177 loans that have reached a final outcome, 14.7 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.

Coverage
What this page does not hold.
Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.
- No NFIP communities are listed for this county in the FEMA Community Status Book.
- Flood zone record counts are not held. The flood coverage export has not landed, so no count is shown rather than an estimated one.
- Traffic counts resolve in the platform, not in this dataset, so no AADT figure is printed here.
- Zoning is in build. Parcel level zoning is not published on this page.

Cities and places in Middlesex.
51 Census places lie wholly or partly in Middlesex County. 51 carry enough published place level data for a page of their own and are linked. The rest are named here and not linked, because the American Community Survey and the SBA record between them do not carry enough about them to write an honest page. A place existing is itself worth knowing, so nothing in the county is left out.

A further 723 SBA approvals in Middlesex County are recorded against borrower cities that match no Census place, the largest being Edison, East Brunswick, North Brunswick. Those are postal cities and unincorporated areas rather than incorporated places, so no page claims them, and their lending is counted in this county's totals above rather than under any city.
