Astoria, SD population, income and ZIP codes

Astoria town is a very small community in South Dakota, with 160 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #260 of 485 ranked by population — larger than 46% of them. The median age here is 38.8 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 Astoria town earn a median of $46,667 a year, 40.6% below the national figure of $78,538 and 29% below the $65,500 median for the 79 South Dakota cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 16.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Astoria town is valued at $103,400, 65.9% below the national figure and 46% below the $192,800 peer median, while median gross rent runs $850 a month, 39.5% below the national figure, or roughly $10,200 across a full year. A household on the local median income would put about 21.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.2×, 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. 80.8% 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 160 residents, a handful of survey responses moves every median on this page. Compare Astoria town 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.
