Webster Groves, MO population, income and ZIP codes

Webster Groves city is a mid-size town in Missouri, with 23,771 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #33 of 1,082 ranked by population — larger than 97% of them. The median age here is 40.3 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 Webster Groves city earn a median of $110,716 a year, 41% above the national figure of $78,538 and 99% 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Webster Groves city is valued at $371,400, 22.4% above the national figure and 144% above the $152,400 peer median, while median gross rent runs $1,628 a month, 15.8% above the national figure, or roughly $19,536 across a full year. A household on the local median income would put about 17.6% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
