Butte ZIP codes — Butte County, South Dakota

Butte County is a mid-size town in South Dakota, with 10,538 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39.3 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Butte County earn a median of $67,692 a year, 13.8% below the national figure of $78,538. 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 7.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Butte County is valued at $207,700, 31.5% below the national figure, while median gross rent runs $940 a month, 33.1% below the national figure, or roughly $11,280 across a full year. A household on the local median income would put about 16.7% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 80.5% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
