Suffolk County, not Islip Terrace
Suffolk County context, not Islip Terrace 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 Islip Terrace 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 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 Islip Terrace. 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.
