Costilla, NM population, income and ZIP codes

Costilla CDP is a very small community in New Mexico, with 498 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #249 of 527 ranked by population — larger than 52% of them. The median age here is 35.3 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Costilla CDP earn a median of not published a year. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Costilla 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.

With 498 residents, a handful of survey responses moves every median on this page. Compare Costilla CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for Costilla 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.
