St. Marks, KS population, income and ZIP codes

St. Marks CDP is a very small community in Kansas, with 87 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #566 of 740 ranked by population — larger than 23% of them. The median age here is 10.9 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 St. Marks CDP earn a median of not published a year. 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in St. Marks CDP is valued at not published, while median gross rent runs not published a month. 33.3% 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 10.9 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 87 residents, a handful of survey responses moves every median on this page. Compare St. Marks CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for St. Marks 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.
