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

- Covered employment, Santa Clara County1,116,581

Every figure in this section is published for Santa Clara County as a whole and is not a measurement of Alum Rock. 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.
- No SBA approvals are recorded to a borrower address in this place in either FOIA release.
- 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.
