Carbon city, IA in context
How this area compares with national benchmarks.
Carbon city is a very small community in Iowa, with 46 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #944 of 1,026 ranked by population — larger than 8% of them. The median age here is 68.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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.

This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 28.3% 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 Carbon city is valued at not published, while median gross rent runs not published a month. 92.9% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
A median age of 68.5 puts Carbon city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 46 residents, a handful of survey responses moves every median on this page. Compare Carbon city against its county rather than against national figures.
The Census withheld household income, home value, gross rent for Carbon 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.
