Sioux ZIP codes — Sioux County, North Dakota

Sioux County is a small town in North Dakota, with 3,789 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 28.7 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Sioux County earn a median of $41,676 a year, 46.9% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 42.7% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Sioux County is valued at $87,400, 71.2% below the national figure, while median gross rent runs $466 a month, 66.9% below the national figure, or roughly $5,592 across a full year. A household on the local median income would put about 13.4% 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 2.1×, 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. 46% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 28.7 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
