Rock, KS population, income and ZIP codes

Rock CDP is a very small community in Kansas, with 123 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #520 of 740 ranked by population — larger than 29% of them. The median age here is 29.8 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 Rock CDP earn a median of $76,786 a year, 2.2% below the national figure of $78,538 and 20% above the $63,750 median for the 200 Kansas cities we cover. 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Rock CDP is valued at not published, while median gross rent runs not published a month. 75% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 29.8 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 123 residents, a handful of survey responses moves every median on this page. Compare Rock CDP against its county rather than against national figures.

The Census withheld home value, gross rent for Rock 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.
