Cameron County, not Port Isabel

Cameron County context, not Port Isabel figures

These are Cameron 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 Isabel measurements.

  • Establishments in Cameron County6,732
  • Employment at those establishments, Cameron County123,749
  • Covered employment, Cameron County156,619
  • Average annual pay, Cameron County$44,590
  • Average weekly wage, Cameron County$857
  • Housing units permitted, Cameron County2,347
  • Of those, single family, Cameron County1,668
  • County product, 2024, Cameron County$17,386,891,000
  • County product change over the prior year, Cameron County8.4 percent
  • Average income of an arriving household, Cameron County$57,350

Every figure in this section is published for Cameron County as a whole and is not a measurement of Port Isabel. 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.
