San Carlos I, TX population, income and ZIP codes

San Carlos I CDP is a very small community in Texas, with 213 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1541 of 1,863 ranked by population — larger than 17% of them. The median age here is 45 years against 39.1 nationally, a slightly older 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 San Carlos I 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 61% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in San Carlos I CDP is valued at not published, while median gross rent runs not published a month. 42.9% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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 213 residents, a handful of survey responses moves every median on this page. Compare San Carlos I CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for San Carlos I 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.
