Mound City, SD population, income and ZIP codes

Mound City town is a very small community in South Dakota, with 97 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #306 of 485 ranked by population — larger than 36% of them. The median age here is 38.3 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 Mound City town earn a median of $43,750 a year, 44.3% below the national figure of $78,538 and 33% below the $65,500 median for the 79 South Dakota 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 36.1% 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 Mound City town is valued at $27,900, 90.8% below the national figure and 86% below the $192,800 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 0.6×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 67.4% 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 97 residents, a handful of survey responses moves every median on this page. Compare Mound City town against its county rather than against national figures.

The Census withheld gross rent for Mound City town 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.
