Contra Costa County, not Byron

Contra Costa County context, not Byron 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 Byron measurements.

  • Establishments in Contra Costa County25,932
  • Employment at those establishments, Contra Costa County343,690
  • Covered employment, Contra Costa County373,992
  • Average annual pay, Contra Costa County$86,234
  • Average weekly wage, Contra Costa County$1,658
  • Housing units permitted, Contra Costa County2,155
  • Of those, single family, Contra Costa County1,251
  • County product, 2024, Contra Costa County$96,579,110,000
  • County product change over the prior year, Contra Costa County1.5 percent
  • 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 Byron. 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.

No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Contra Costa 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 Byron.

Is zoning published for Byron?

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