Suffolk County, not Port Jefferson
Suffolk County context, not Port Jefferson figures
These are Suffolk County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Port Jefferson measurements.
- Establishments in Suffolk County50,748
- Employment at those establishments, Suffolk County592,580
- Covered employment, Suffolk County679,594
- Average annual pay, Suffolk County$79,121
- Average weekly wage, Suffolk County$1,522
- Housing units permitted, Suffolk County1,407
- Of those, single family, Suffolk County1,137
- County product, 2024, Suffolk County$139,014,125,000
- County product change over the prior year, Suffolk County5.9 percent
- Average income of an arriving household, Suffolk County$144,254
Every figure in this section is published for Suffolk County as a whole and is not a measurement of Port Jefferson. 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 Port Jefferson businesses?
25 7(a) approvals totalling $12.7 m, across 14 lenders, median approval $150,000, plus 5 504 approvals worth $4.5 m. These count approvals to borrowers whose address is in Port Jefferson, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Port Jefferson borrowers get paid back?
No rate is published for Port Jefferson. only 4 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 Port Jefferson in the National Flood Insurance Program?
Yes. Port Jefferson appears in the FEMA Community Status Book as community 360804, 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 Port Jefferson figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Suffolk 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 Port Jefferson.
Is zoning published for Port Jefferson?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
