Mount Vernon, MO population, income and ZIP codes

Mount Vernon city is a small town in Missouri, with 4,532 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #162 of 1,082 ranked by population — larger than 85% of them. The median age here is 35.3 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 Mount Vernon city earn a median of $49,153 a year, 37.4% below the national figure of $78,538 and 12% 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. Poverty reaches 18.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Mount Vernon city is valued at $175,000, 42.3% below the national figure and 15% above the $152,400 peer median, while median gross rent runs $691 a month, 50.9% below the national figure, or roughly $8,292 across a full year. A household on the local median income would put about 16.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 56.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

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.
