El Castillo, TX population, income and ZIP codes

El Castillo CDP is a very small community in Texas, with 307 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1431 of 1,863 ranked by population — larger than 23% of them. The median age here is 18.8 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 El Castillo 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 39.7% 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 El Castillo CDP is valued at not published, while median gross rent runs not published a month. 28.8% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 18.8 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 307 residents, a handful of survey responses moves every median on this page. Compare El Castillo CDP against its county rather than against national figures.

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