Duval County, not San Diego
Duval County context, not San Diego figures
These are Duval County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as San Diego measurements.
- Establishments in Duval County144
- Employment at those establishments, Duval County1,977
- Covered employment, Duval County3,673
- Average annual pay, Duval County$40,727
- Average weekly wage, Duval County$783
- County product, 2024, Duval County$346,579,000
- County product change over the prior year, Duval County-12.5 percent
- Average income of an arriving household, Duval County$40,665
Every figure in this section is published for Duval County as a whole and is not a measurement of San Diego. 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.
Common questions
San Diego questions, answered from the record.
How many people live in San Diego, Texas?
3,675, in 1,253 households. San Diego city covers 1.90 square miles of land, which is 1,933 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.
What county is San Diego in?
San Diego lies in more than one. By area it is 77.3 percent in Duval County, 22.7 percent in Jim Wells County. This page sits under Duval County because that county holds the largest share. The split is measured from the Census boundary of the place against the county boundaries.
What is the median household income in San Diego?
$53,174. The median owner-occupied home is valued at $85,600. Median gross rent is $1,096 per month. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.
Is San Diego in the National Flood Insurance Program?
Yes. San Diego appears in the FEMA Community Status Book as community 481199, with no Community Rating System class, so no CRS discount applies. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.
Are the county figures on this page San Diego figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Duval 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 San Diego.
Is zoning published for San Diego?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
