Maryland Heights, MO population, income and ZIP codes

Maryland Heights city is a small city in Missouri, with 27,981 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #26 of 1,082 ranked by population — larger than 97% of them. The median age here is 34.8 years against 39.1 nationally, a slightly younger 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 Maryland Heights city earn a median of $86,485 a year, 10.1% above the national figure of $78,538 and 56% above 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. Poverty reaches 5.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Maryland Heights city is valued at $215,300, 29% below the national figure and 41% above the $152,400 peer median, while median gross rent runs $1,217 a month, 13.4% below the national figure, or roughly $14,604 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 57.6% 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.

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.
