Cook County, not Blue Island
Cook County context, not Blue Island figures
These are Cook County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Blue Island measurements.
- Establishments in Cook County134,513
- Employment at those establishments, Cook County2,492,328
- Covered employment, Cook County2,565,567
- Average annual pay, Cook County$86,931
- Average weekly wage, Cook County$1,672
- Housing units permitted, Cook County6,507
- Of those, single family, Cook County1,142
- County product, 2024, Cook County$546,440,623,000
- County product change over the prior year, Cook County4.6 percent
- Average income of an arriving household, Cook County$91,691
Every figure in this section is published for Cook County as a whole and is not a measurement of Blue Island. 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 Blue Island businesses?
25 7(a) approvals totalling $11.8 m, across 10 lenders, median approval $135,000, plus 7 504 approvals worth $3.5 m. These count approvals to borrowers whose address is in Blue Island, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Blue Island borrowers get paid back?
No rate is published for Blue Island. only 3 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 Blue Island in the National Flood Insurance Program?
Yes. Blue Island appears in the FEMA Community Status Book as community 170064, 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 Blue Island figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Cook 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 Blue Island.
Is zoning published for Blue Island?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
