Mercer County, not Princeton Junction
Mercer County context, not Princeton Junction 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 Princeton Junction measurements.

- Employment at those establishments, Mercer County208,192
- Covered employment, Mercer County264,154
- Average annual pay, Mercer County$90,503

- Average income of an arriving household, Mercer County$120,760
Every figure in this section is published for Mercer County as a whole and is not a measurement of Princeton Junction. 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.
