Corwith, IA population, income and ZIP codes

Corwith city is a very small community in Iowa, with 270 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #627 of 1,026 ranked by population — larger than 38% of them. The median age here is 44.8 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 Corwith city earn a median of $55,481 a year, 29.4% below the national figure of $78,538 and 18% 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 37.4% 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 Corwith city is valued at $58,100, 80.9% below the national figure and 63% below the $156,300 peer median, while median gross rent runs $944 a month, 32.9% below the national figure, or roughly $11,328 across a full year. A household on the local median income would put about 20.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 1×, 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. 76.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 270 residents, a handful of survey responses moves every median on this page. Compare Corwith city against its county rather than against national figures.
