Marin County, not Alto
Marin County context, not Alto figures
These are Marin County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Alto measurements.
- Establishments in Marin County10,049
- Employment at those establishments, Marin County106,249
- Covered employment, Marin County110,934
- Average annual pay, Marin County$93,552
- Average weekly wage, Marin County$1,799
- Housing units permitted, Marin County158
- Of those, single family, Marin County151
- County product, 2024, Marin County$36,853,590,000
- County product change over the prior year, Marin County3.9 percent
- Average income of an arriving household, Marin County$309,655
Every figure in this section is published for Marin County as a whole and is not a measurement of Alto. 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.
- No median owner-occupied home value is published for this place.
- No median gross rent is published for this place.
- 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.

Are the county figures on this page Alto figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Marin 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 Alto.
Is zoning published for Alto?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
