Sullivan, MO population, income and ZIP codes

Sullivan city is a mid-size town in Missouri, with 6,355 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #122 of 1,082 ranked by population — larger than 88% of them. The median age here is 41.9 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Sullivan city earn a median of $60,137 a year, 23.4% below the national figure of $78,538 and 8% above the $55,543 median for the 374 Missouri cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 12.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Sullivan city is valued at $153,100, 49.5% below the national figure and within a couple of points of the $152,400 peer median, while median gross rent runs $862 a month, 38.7% below the national figure, or roughly $10,344 across a full year. A household on the local median income would put about 17.2% 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 68.6% 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.

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.
