Nassau County, not Seaford
Nassau County context, not Seaford figures
These are Nassau County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Seaford measurements.
- Establishments in Nassau County48,718
- Employment at those establishments, Nassau County562,420
- Covered employment, Nassau County631,563
- Average annual pay, Nassau County$77,454
- Average weekly wage, Nassau County$1,489
- Housing units permitted, Nassau County830
- Of those, single family, Nassau County607
- County product, 2024, Nassau County$130,221,948,000
- County product change over the prior year, Nassau County3.7 percent
- Average income of an arriving household, Nassau County$131,119
Every figure in this section is published for Nassau County as a whole and is not a measurement of Seaford. 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.
- This place is not listed as a community in the FEMA Community Status Book, so no NFIP participation or CRS class is shown.
- 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.

24 7(a) approvals totalling $10.0 m, across 13 lenders, median approval $190,000, plus 3 504 approvals worth $1.1 m. These count approvals to borrowers whose address is in Seaford, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Seaford borrowers get paid back?
No rate is published for Seaford. 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.
Are the county figures on this page Seaford figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Nassau 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 Seaford.
Is zoning published for Seaford?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
