Flandreau, SD population, income and ZIP codes

Flandreau city is a small town in South Dakota, with 2,291 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #40 of 485 ranked by population — larger than 91% of them. The median age here is 37 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 Flandreau city earn a median of $56,458 a year, 28.1% below the national figure of $78,538 and 14% 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 18.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Flandreau city is valued at $130,800, 56.9% below the national figure and 32% below the $192,800 peer median, while median gross rent runs $689 a month, 51% below the national figure, or roughly $8,268 across a full year. A household on the local median income would put about 14.6% 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 2.3×, 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. 54.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
