This is a small place, and the figures below carry wide margins.

The American Community Survey reaches Port Costa through a sample, not a count, and in a place this size that sample is thin. The population estimate here is 296 with a margin of error of plus or minus 167, which is 56.4 percent of the estimate itself. Every figure whose margin reaches 20 percent is printed with that margin beside it, so you can see the width of each one rather than having to assume it.

Nothing has been removed or adjusted. These are the published federal estimates, shown with the uncertainty the Census publishes alongside them.

Contra Costa County, not Port Costa

Contra Costa County context, not Port Costa 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 Port Costa 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 Port Costa. 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 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.
