Martinsburg, MO population, income and ZIP codes

Martinsburg town is a very small community in Missouri, with 582 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #485 of 1,082 ranked by population — larger than 55% of them. The median age here is 39.6 years against 39.1 nationally, a slightly older 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 Martinsburg town earn a median of $31,735 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. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table.

The typical owner-occupied home in Martinsburg town is valued at not published, while median gross rent runs $432 a month, 69.3% below the national figure, or roughly $5,184 across a full year. A household on the local median income would put about 16.3% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. 85.5% 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.

The Census withheld home value for Martinsburg town 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.
