Decorah city, IA in context
How this area compares with national benchmarks.
Decorah city is a mid-size town in Iowa, with 7,597 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #53 of 1,026 ranked by population — larger than 94% of them. The median age here is 36.5 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 Decorah city earn a median of $62,177 a year, 20.8% below the national figure of $78,538 and 8% below 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 7.7% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Decorah city is valued at $234,600, 22.7% below the national figure and 50% above the $156,300 peer median, while median gross rent runs $788 a month, 44% below the national figure, or roughly $9,456 across a full year. A household on the local median income would put about 15.2% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 64.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
