Hamilton, IA population, income and ZIP codes

Hamilton city is a very small community in Iowa, with 87 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #877 of 1,026 ranked by population — larger than 14% of them. The median age here is 35.5 years against 39.1 nationally, a slightly younger 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 Hamilton city earn a median of $70,000 a year, 10.9% below the national figure of $78,538 and 3% 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 3.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Hamilton city is valued at not published, while median gross rent runs not published a month. 94.4% 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.

With 87 residents, a handful of survey responses moves every median on this page. Compare Hamilton city against its county rather than against national figures.

The Census withheld home value, gross rent for Hamilton 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.
