Marshalltown city, IA in context

How this area compares with national benchmarks.

Marshalltown city is a small city in Iowa, with 27,491 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #16 of 1,026 ranked by population — larger than 98% of them. The median age here is 35.7 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Marshalltown city earn a median of $68,854 a year, 12.3% below the national figure of $78,538 and within a couple of points of the $67,791 median for the 290 Iowa cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 14% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Marshalltown city is valued at $117,100, 61.4% below the national figure and 25% below the $156,300 peer median, while median gross rent runs $864 a month, 38.5% below the national figure, or roughly $10,368 across a full year. A household on the local median income would put about 15.1% 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 1.7×, 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. 66.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
