Calmar, IA population, income and ZIP codes

Calmar city is a very small community in Iowa, with 980 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #294 of 1,026 ranked by population — larger than 71% of them. The median age here is 31.7 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Calmar city earn a median of $81,583 a year, 3.9% above the national figure of $78,538 and 20% above 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 10.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Calmar city is valued at $194,600, 35.9% below the national figure and 25% above the $156,300 peer median, while median gross rent runs $684 a month, 51.4% below the national figure, or roughly $8,208 across a full year. A household on the local median income would put about 10.1% 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 2.4×, 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. 73.5% 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.
