Decatur, IA population, income and housing data

Decatur city is a very small community in Iowa, with 163 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #747 of 1,026 ranked by population — larger than 27% of them. The median age here is 38.8 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Decatur city earn a median of $33,750 a year, 57% below the national figure of $78,538 and 50% below the $67,791 median for the 290 Iowa cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 31.3% 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 Decatur city is valued at $84,200, 72.2% below the national figure and 46% below the $156,300 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 95.5% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 163 residents, a handful of survey responses moves every median on this page. Compare Decatur city against its county rather than against national figures.

The Census withheld gross rent for Decatur 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.
