Sioux Rapids, IA population, income and ZIP codes

Sioux Rapids city is a very small community in Iowa, with 831 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #340 of 1,026 ranked by population — larger than 66% of them. The median age here is 46 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Rapids city earn a median of $56,307 a year, 28.3% below the national figure of $78,538 and 17% below the $67,791 median for the 290 Iowa cities we cover. 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 5.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Sioux Rapids city is valued at $84,400, 72.2% below the national figure and 46% below the $156,300 peer median, while median gross rent runs $641 a month, 54.4% below the national figure, or roughly $7,692 across a full year. A household on the local median income would put about 13.7% 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 1.5×, 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. 81.8% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
