Richmond Heights, MO population, income and ZIP codes

Richmond Heights city is a mid-size town in Missouri, with 9,179 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #90 of 1,082 ranked by population — larger than 91% of them. The median age here is 35.4 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 Richmond Heights city earn a median of $90,670 a year, 15.4% above the national figure of $78,538 and 63% 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 5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Richmond Heights city is valued at $345,400, 13.8% above the national figure and 127% above the $152,400 peer median, while median gross rent runs $1,447 a month, 2.9% above the national figure, or roughly $17,364 across a full year. A household on the local median income would put about 19.2% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 51.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
