Mercer County, not West Middlesex
Mercer County context, not West Middlesex figures
These are Mercer County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as West Middlesex measurements.

- Covered employment, Mercer County43,239
- Average annual pay, Mercer County$54,120

- Average income of an arriving household, Mercer County$57,788
Every figure in this section is published for Mercer County as a whole and is not a measurement of West Middlesex. 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.
