Sunset Hills, MO population, income and ZIP codes

Sunset Hills city is a mid-size town in Missouri, with 9,113 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #93 of 1,082 ranked by population — larger than 91% of them. The median age here is 50.2 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 Sunset Hills city earn a median of $133,895 a year, 70.5% above the national figure of $78,538 and 141% 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 2.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Sunset Hills city is valued at $522,300, 72.1% above the national figure and 243% above the $152,400 peer median, while median gross rent runs $3,454 a month, 145.7% above the national figure, or roughly $41,448 across a full year. A household on the local median income would put about 31% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.6% 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.

A median age of 50.2 puts Sunset Hills city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

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.
