Macon County, not Decatur
Macon County context, not Decatur figures
These are Macon County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Decatur measurements.
- Establishments in Macon County2,241
- Employment at those establishments, Macon County42,511
- Covered employment, Macon County45,051
- Average annual pay, Macon County$67,788
- Average weekly wage, Macon County$1,304
- Housing units permitted, Macon County57
- Of those, single family, Macon County39
- County product, 2024, Macon County$9,053,686,000
- County product change over the prior year, Macon County2.9 percent
- Average income of an arriving household, Macon County$49,647
Every figure in this section is published for Macon County as a whole and is not a measurement of Decatur. 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.
- 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.

How much SBA lending goes to Decatur businesses?
76 7(a) approvals totalling $52.1 m, across 20 lenders, median approval $300,000, plus 28 504 approvals worth $19.4 m. These count approvals to borrowers whose address is in Decatur, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Decatur borrowers get paid back?
Of the 10 loans that have reached a final outcome, 10 were paid in full and 0 charged off, a charge off rate of 0.0 percent. Loans still running are excluded because they have not yet succeeded or failed.
Is Decatur in the National Flood Insurance Program?
Yes. Decatur appears in the FEMA Community Status Book as community 170429, with no Community Rating System class, so no CRS discount applies. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.
Are the county figures on this page Decatur figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Macon 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 Decatur.
Is zoning published for Decatur?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
