Residents under 18 outnumber those 65 and over, at 17.5 percent against 16.4 percent, a household formation profile rather than a retirement one.

The average approval of $537,915 sits well above the median of $250,000, 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 9.0 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 Boulder County
Do SBA loans in Boulder County get paid back?

- Paid in full113
- Charged off10
- Charge off rate on resolved loans8.1 percent
- Status: Paid in full113
- Status: Exempt from disclosure416
- Status: Charged off10
- Status: Cancelled82
- Status: Committed, not yet disbursed45
Of the 123 loans that have reached a final outcome, 8.1 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 Boulder.
33 Census places lie wholly or partly in Boulder County. 32 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 2,425 SBA approvals in Boulder County are recorded against borrower cities that match no Census place, the largest being Denver, Broomfield, Eric. 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.
