Irondale, MO population, income and ZIP codes

Irondale city is a very small community in Missouri, with 534 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #507 of 1,082 ranked by population — larger than 53% of them. The median age here is 35.6 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 Irondale city earn a median of $31,750 a year, 59.6% below the national figure of $78,538 and 43% below the $55,543 median for the 374 Missouri cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 34.8% 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 Irondale city is valued at $100,000, 67% below the national figure and 34% below the $152,400 peer median, while median gross rent runs $1,000 a month, 28.9% below the national figure, or roughly $12,000 across a full year. A household on the local median income would put about 37.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.4% 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.

Irondale city is the unusual combination of expensive to rent and cheap to buy: rent takes 37.8% of median income while homes cost only 3.1× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price. With 534 residents, a handful of survey responses moves every median on this page. Compare Irondale city against its county rather than against national figures.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
