San Mateo County, not Atherton
San Mateo County context, not Atherton figures
These are San Mateo County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Atherton measurements.
- Establishments in San Mateo County21,569
- Employment at those establishments, San Mateo County477,938
- Covered employment, San Mateo County416,422
- Average annual pay, San Mateo County$196,441
- Average weekly wage, San Mateo County$3,778
- Housing units permitted, San Mateo County1,088
- Of those, single family, San Mateo County521

- County product change over the prior year, San Mateo County11.1 percent
- Average income of an arriving household, San Mateo County$211,636
Every figure in this section is published for San Mateo County as a whole and is not a measurement of Atherton. 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.

Do SBA loans to Atherton borrowers get paid back?
No rate is published for Atherton. only 0 resolved loans, too few to publish a rate, and a percentage over that few outcomes would move several points on a single loan. The counts are shown instead.
Is Atherton in the National Flood Insurance Program?
Yes. Atherton appears in the FEMA Community Status Book as community 060312, with no Community Rating System class, so no CRS discount applies. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.
Are the county figures on this page Atherton figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for San Mateo 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 Atherton.
Is zoning published for Atherton?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
