Knollwood, TX population, income and ZIP codes

Knollwood city is a very small community in Texas, with 488 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1282 of 1,863 ranked by population — larger than 31% of them. The median age here is 33.5 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 Knollwood city earn a median of $61,250 a year, 22% below the national figure of $78,538 and 5% below the $64,654 median for the 1,008 Texas cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 8.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Knollwood city is valued at not published, while median gross rent runs $1,259 a month, 10.5% below the national figure, or roughly $15,108 across a full year. A household on the local median income would put about 24.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 31.5% 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.

The Census withheld home value for Knollwood city 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.
