Old Monroe, MO population, income and ZIP codes

Old Monroe city is a very small community in Missouri, with 183 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #760 of 1,082 ranked by population — larger than 29% of them. The median age here is 30.5 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 Old Monroe city earn a median of $61,458 a year, 21.7% below the national figure of $78,538 and 11% above the $55,543 median for the 374 Missouri cities we cover. 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 4.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Old Monroe city is valued at $154,200, 49.2% below the national figure and within a couple of points of the $152,400 peer median, while median gross rent runs $1,156 a month, 17.8% below the national figure, or roughly $13,872 across a full year. A household on the local median income would put about 22.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 81.5% 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 183 residents, a handful of survey responses moves every median on this page. Compare Old Monroe city against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
