DuPage County, not Naperville
DuPage County context, not Naperville 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 Naperville 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
- Of those, single family, DuPage County784
- County product, 2024, DuPage County$129,734,015,000
- 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 Naperville. 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
Naperville questions, answered from the record.
How many people live in Naperville, Illinois?
150,692, in 54,847 households. Naperville city covers 39.35 square miles of land, which is 3,829 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.
What county is Naperville in?
Naperville lies in more than one. By area it is 65.4 percent in DuPage County, 34.6 percent in Will County. This page sits under DuPage County because that county holds the largest share. The split is measured from the Census boundary of the place against the county boundaries.
What is the median household income in Naperville?
$155,105. The median owner-occupied home is valued at $540,200. Median gross rent is $1,885 per month. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.
How much SBA lending goes to Naperville businesses?
322 7(a) approvals totalling $137.6 m, across 60 lenders, median approval $200,000, plus 92 504 approvals worth $78.8 m. These count approvals to borrowers whose address is in Naperville, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Naperville borrowers get paid back?
Of the 61 loans that have reached a final outcome, 56 were paid in full and 5 charged off, a charge off rate of 8.2 percent. Loans still running are excluded because they have not yet succeeded or failed.
Is Naperville in the National Flood Insurance Program?
Yes. Naperville appears in the FEMA Community Status Book as community 170213, carrying Community Rating System class 10, which is a premium discount for exceeding the programme minimum. 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 Naperville 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 Naperville.
Is zoning published for Naperville?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
