Contra Costa County, not Bethel Island
Contra Costa County context, not Bethel Island figures
These are Contra Costa County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Bethel Island measurements.

- Employment at those establishments, Contra Costa County343,690
- Covered employment, Contra Costa County373,992
- Average annual pay, Contra Costa County$86,234

- Average income of an arriving household, Contra Costa County$162,744
Every figure in this section is published for Contra Costa County as a whole and is not a measurement of Bethel Island. 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.
