Allerton, IA population, income and ZIP codes

Allerton city is a very small community in Iowa, with 413 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #515 of 1,026 ranked by population — larger than 49% of them. The median age here is 44.5 years against 39.1 nationally, a slightly older 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 Allerton city earn a median of $45,417 a year, 42.2% below the national figure of $78,538 and 33% 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 25.2% 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 Allerton city is valued at $85,000, 72% below the national figure and 46% below the $156,300 peer median, while median gross rent runs $583 a month, 58.5% below the national figure, or roughly $6,996 across a full year. A household on the local median income would put about 15.4% 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 1.9×, 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. 79.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

With 413 residents, a handful of survey responses moves every median on this page. Compare Allerton city against its county rather than against national figures.
