Grassland Colony, SD population, income and ZIP codes

Grassland Colony CDP is a very small community in South Dakota, with 36 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #389 of 485 ranked by population — larger than 19% of them. The median age here is 45 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 Grassland Colony CDP earn a median of not published a year. 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 Grassland Colony CDP is valued at not published, while median gross rent runs not published a month. 100% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 36 residents, a handful of survey responses moves every median on this page. Compare Grassland Colony CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for Grassland Colony CDP because the sample was too thin to publish at this geography.
