Alameda County, not Castro Valley
Alameda County context, not Castro Valley figures
These are Alameda County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Castro Valley measurements.
- Establishments in Alameda County42,318
- Employment at those establishments, Alameda County749,124
- Covered employment, Alameda County790,358
- Average annual pay, Alameda County$98,026
- Average weekly wage, Alameda County$1,885
- Housing units permitted, Alameda County1,743
- Of those, single family, Alameda County826
- County product, 2024, Alameda County$182,539,223,000
- County product change over the prior year, Alameda County3.9 percent
- Average income of an arriving household, Alameda County$142,638
Every figure in this section is published for Alameda County as a whole and is not a measurement of Castro Valley. 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.

Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
