Yankton ZIP codes — Yankton County, South Dakota

Yankton County is a mid-size town in South Dakota, with 23,379 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 42.2 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 Yankton County earn a median of $73,855 a year, 6% 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 9.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Yankton County is valued at $208,200, 31.4% below the national figure, while median gross rent runs $777 a month, 44.7% below the national figure, or roughly $9,324 across a full year. A household on the local median income would put about 12.6% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 72.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
