Superior city, IA in context

How this area compares with national benchmarks.

Superior city is a very small community in Iowa, with 132 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #799 of 1,026 ranked by population — larger than 22% of them. The median age here is 47.4 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 Superior city earn a median of $59,432 a year, 24.3% below the national figure of $78,538 and 12% below 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 6.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Superior city is valued at $74,000, 75.6% below the national figure and 53% below the $156,300 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.2×, 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. 98.2% 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.

With 132 residents, a handful of survey responses moves every median on this page. Compare Superior city against its county rather than against national figures.

The Census withheld gross rent for Superior city because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
