Walnut Grove, MO population, income and ZIP codes

Walnut Grove city is a very small community in Missouri, with 566 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #493 of 1,082 ranked by population — larger than 54% of them. The median age here is 46.6 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Walnut Grove city earn a median of $45,357 a year, 42.2% below the national figure of $78,538 and 18% 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.

The typical owner-occupied home in Walnut Grove city is valued at $127,600, 57.9% below the national figure and 16% below the $152,400 peer median, while median gross rent runs $733 a month, 47.9% below the national figure, or roughly $8,796 across a full year. A household on the local median income would put about 19.4% 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. 67.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
