Delaware County, not Darby
Delaware County context, not Darby figures
These are Delaware County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Darby measurements.
- Establishments in Delaware County13,165
- Employment at those establishments, Delaware County237,233
- Covered employment, Delaware County218,536
- Average annual pay, Delaware County$73,172
- Average weekly wage, Delaware County$1,407
- Housing units permitted, Delaware County281
- Of those, single family, Delaware County267
- County product, 2024, Delaware County$42,607,881,000
- County product change over the prior year, Delaware County3.4 percent
- Average income of an arriving household, Delaware County$98,103
Every figure in this section is published for Delaware County as a whole and is not a measurement of Darby. 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 Darby businesses?
15 7(a) approvals totalling $2.9 m, across 10 lenders, median approval $80,000. These count approvals to borrowers whose address is in Darby, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Darby borrowers get paid back?
No rate is published for Darby. only 4 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.
Is Darby in the National Flood Insurance Program?
Yes. Darby appears in the FEMA Community Status Book as community 421603, 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 Darby figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Delaware 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 Darby.
Is zoning published for Darby?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
