Armstrong, MO population, income and ZIP codes

Armstrong city is a very small community in Missouri, with 340 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #622 of 1,082 ranked by population — larger than 42% of them. The median age here is 33.8 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 Armstrong city earn a median of $39,667 a year, 49.5% below the national figure of $78,538 and 29% below the $55,543 median for the 374 Missouri 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 10.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Armstrong city is valued at not published, while median gross rent runs not published a month. 90.3% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 340 residents, a handful of survey responses moves every median on this page. Compare Armstrong city against its county rather than against national figures.

The Census withheld home value, gross rent for Armstrong 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.
