Thor city, IA in context
How this area compares with national benchmarks.
Thor city is a very small community in Iowa, with 276 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #623 of 1,026 ranked by population — larger than 39% of them. The median age here is 28.2 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 Thor city earn a median of $56,250 a year, 28.4% below the national figure of $78,538 and 17% below the $67,791 median for the 290 Iowa cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 44.6% 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 Thor city is valued at not published, while median gross rent runs $979 a month, 30.4% below the national figure, or roughly $11,748 across a full year. A household on the local median income would put about 20.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 85.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.
A median age of 28.2 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 276 residents, a handful of survey responses moves every median on this page. Compare Thor city against its county rather than against national figures.
The Census withheld home value for Thor city because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
