San Mateo, NM population, income and ZIP codes

San Mateo CDP is a very small community in New Mexico, with 726 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #198 of 527 ranked by population — larger than 62% of them. The median age here is 25.7 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in San Mateo CDP earn a median of not published a year. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in San Mateo CDP is valued at not published, while median gross rent runs not published a month. 100% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

A median age of 25.7 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 726 residents, a handful of survey responses moves every median on this page. Compare San Mateo CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for San Mateo CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
