Middlesex County, not Jamesburg
Middlesex County context, not Jamesburg figures
These are Middlesex County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Jamesburg measurements.
- Establishments in Middlesex County22,314
- Employment at those establishments, Middlesex County434,143
- Covered employment, Middlesex County430,555
- Average annual pay, Middlesex County$82,400
- Average weekly wage, Middlesex County$1,585
- Housing units permitted, Middlesex County1,792
- Of those, single family, Middlesex County677
- County product, 2024, Middlesex County$86,704,508,000
- County product change over the prior year, Middlesex County4.3 percent
- Average income of an arriving household, Middlesex County$90,589
Every figure in this section is published for Middlesex County as a whole and is not a measurement of Jamesburg. 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.
