Sioux Center, IA population, income and ZIP codes

Sioux Center city is a mid-size town in Iowa, with 8,335 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #47 of 1,026 ranked by population — larger than 95% of them. The median age here is 29.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Sioux Center city earn a median of $87,555 a year, 11.5% above the national figure of $78,538 and 29% above the $67,791 median for the 290 Iowa cities we cover. 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 1.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Sioux Center city is valued at $275,900, 9.1% below the national figure and 77% above the $156,300 peer median, while median gross rent runs $884 a month, 37.1% below the national figure, or roughly $10,608 across a full year. A household on the local median income would put about 12.1% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.8% 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.

A median age of 29.3 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.
