Ballwin city, MO in context

How this area compares with national benchmarks.

Ballwin city is a small city in Missouri, with 30,835 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #21 of 1,082 ranked by population — larger than 98% of them. The median age here is 42.3 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 Ballwin city earn a median of $121,170 a year, 54.3% above the national figure of $78,538 and 118% above the $55,543 median for the 374 Missouri cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 5.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Ballwin city is valued at $353,400, 16.5% above the national figure and 132% above the $152,400 peer median, while median gross rent runs $1,386 a month, 1.4% below the national figure, or roughly $16,632 across a full year. A household on the local median income would put about 13.7% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 83.6% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
