Miami-Dade County, not Key Biscayne
Miami-Dade County context, not Key Biscayne figures
These are Miami-Dade County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Key Biscayne measurements.
- Establishments in Miami-Dade County98,394
- Employment at those establishments, Miami-Dade County1,055,440
- Covered employment, Miami-Dade County1,257,569
- Average annual pay, Miami-Dade County$77,609
- Average weekly wage, Miami-Dade County$1,492
- Housing units permitted, Miami-Dade County10,608
- Of those, single family, Miami-Dade County2,231
- County product, 2024, Miami-Dade County$260,837,199,000
- County product change over the prior year, Miami-Dade County6.6 percent
- Average income of an arriving household, Miami-Dade County$175,619
Every figure in this section is published for Miami-Dade County as a whole and is not a measurement of Key Biscayne. 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 Key Biscayne businesses?
15 7(a) approvals totalling $11.4 m, across 13 lenders, median approval $150,000, plus 2 504 approvals worth $643,000. These count approvals to borrowers whose address is in Key Biscayne, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Key Biscayne borrowers get paid back?
No rate is published for Key Biscayne. only 2 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 Key Biscayne in the National Flood Insurance Program?
Yes. Key Biscayne appears in the FEMA Community Status Book as community 120648, carrying Community Rating System class 8, 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 Key Biscayne figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Miami-Dade 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 Key Biscayne.
Is zoning published for Key Biscayne?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
