Rock Island, TX population, income and ZIP codes

Rock Island CDP is a very small community in Texas, with 371 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1370 of 1,863 ranked by population — larger than 26% of them. The median age here is 39.8 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 Rock Island CDP earn a median of $38,409 a year, 51.1% below the national figure of $78,538 and 41% below the $64,654 median for the 1,008 Texas cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 22.6% 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 Rock Island CDP is valued at not published, while median gross rent runs not published a month. 79.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 371 residents, a handful of survey responses moves every median on this page. Compare Rock Island CDP against its county rather than against national figures.

The Census withheld home value, gross rent for Rock Island 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.
