DuPage County, not Darien
DuPage County context, not Darien figures
These are DuPage County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Darien measurements.
- Establishments in DuPage County34,121
- Employment at those establishments, DuPage County595,691
- Covered employment, DuPage County622,113
- Average annual pay, DuPage County$79,674
- Average weekly wage, DuPage County$1,532
- Housing units permitted, DuPage County1,450

- County product change over the prior year, DuPage County3.4 percent
- Average income of an arriving household, DuPage County$102,362
Every figure in this section is published for DuPage County as a whole and is not a measurement of Darien. 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.
Common questions

How many people live in Darien, Illinois?
21,879, in 8,735 households. Darien city covers 6.17 square miles of land, which is 3,544 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.

DuPage County, which holds 100.0 percent of the place by area. Source: US Census Bureau, cartographic boundary file, places, 2024 vintage.

$111,215. The median owner-occupied home is valued at $398,700. Median gross rent is $1,857 per month. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.
How much SBA lending goes to Darien businesses?
30 7(a) approvals totalling $8.3 m, across 10 lenders, median approval $100,000, plus 11 504 approvals worth $6.7 m. These count approvals to borrowers whose address is in Darien, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Darien borrowers get paid back?
No rate is published for Darien. 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.
Is Darien in the National Flood Insurance Program?
Yes. Darien appears in the FEMA Community Status Book as community 170750, 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 Darien figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for DuPage 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 Darien.
Is zoning published for Darien?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
