Oakville, MO population, income and ZIP codes

Oakville CDP is a small city in Missouri, with 35,166 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #19 of 1,082 ranked by population — larger than 98% of them. The median age here is 45.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Oakville CDP earn a median of $103,125 a year, 31.3% above the national figure of $78,538 and 86% above 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 5.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Oakville CDP is valued at $292,500, 3.6% below the national figure and 92% above the $152,400 peer median, while median gross rent runs $1,083 a month, 23% below the national figure, or roughly $12,996 across a full year. A household on the local median income would put about 12.6% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 86.5% 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. 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.

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.
