Spartanburg County, not Duncan
Spartanburg County context, not Duncan figures
These are Spartanburg County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Duncan measurements.

- Employment at those establishments, Spartanburg County150,332
- Covered employment, Spartanburg County155,484
- Average annual pay, Spartanburg County$59,564
- Average weekly wage, Spartanburg County$1,145
- Housing units permitted, Spartanburg County3,129

- Average income of an arriving household, Spartanburg County$59,513
Every figure in this section is published for Spartanburg County as a whole and is not a measurement of Duncan. It is here because a county backdrop is what a credit committee reads a place against, and it is labelled so that it can never be quoted as the place's own.

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.
- This place is not listed as a community in the FEMA Community Status Book, so no NFIP participation or CRS class is shown.
- Parcel level detail, zoning and flood zone at an address are resolved in the platform, not on this page.
SBA figures count approvals to borrowers whose address is in the place. They are not approvals for projects inside the place boundary: the tape records a borrower city and a project county, and those can differ.

35 7(a) approvals totalling $23.7 m, across 18 lenders, median approval $250,000, plus 4 504 approvals worth $4.7 m. These count approvals to borrowers whose address is in Duncan, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Duncan borrowers get paid back?
No rate is published for Duncan. only 5 resolved loans, too few to publish a rate, and a percentage over that few outcomes would move several points on a single loan. The counts are shown instead.
Are the county figures on this page Duncan figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Spartanburg County as a whole and there is no place level equivalent. They appear in one clearly marked section as context and are never presented as measurements of Duncan.
Is zoning published for Duncan?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
