Middlesex County, not Waltham
Middlesex County context, not Waltham 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 Waltham measurements.
- Establishments in Middlesex County44,624
- Employment at those establishments, Middlesex County963,417
- Covered employment, Middlesex County926,104
- Average annual pay, Middlesex County$113,704
- Average weekly wage, Middlesex County$2,187
- Housing units permitted, Middlesex County3,495
- Of those, single family, Middlesex County889
- County product, 2024, Middlesex County$240,665,230,000
- County product change over the prior year, Middlesex County5.8 percent
- Average income of an arriving household, Middlesex County$129,274
Every figure in this section is published for Middlesex County as a whole and is not a measurement of Waltham. 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.

How much SBA lending goes to Waltham businesses?
101 7(a) approvals totalling $32.9 m, across 31 lenders, median approval $153,000, plus 35 504 approvals worth $26.9 m. These count approvals to borrowers whose address is in Waltham, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Waltham borrowers get paid back?
Of the 19 loans that have reached a final outcome, 18 were paid in full and 1 charged off, a charge off rate of 5.3 percent. Loans still running are excluded because they have not yet succeeded or failed.
Are the county figures on this page Waltham figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Middlesex 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 Waltham.
Is zoning published for Waltham?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
