De Smet, SD population, income and ZIP codes

De Smet city is a very small community in South Dakota, with 974 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #83 of 485 ranked by population — larger than 83% of them. The median age here is 53.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 De Smet city earn a median of $60,139 a year, 23.4% below the national figure of $78,538 and 8% below the $65,500 median for the 79 South Dakota cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 5.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in De Smet city is valued at $155,900, 48.6% below the national figure and 19% below the $192,800 peer median, while median gross rent runs $743 a month, 47.2% below the national figure, or roughly $8,916 across a full year. A household on the local median income would put about 14.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 79.5% 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.

A median age of 53.2 puts De Smet city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 974 residents, a handful of survey responses moves every median on this page. Compare De Smet city against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
