Weldon Spring, MO population, income and ZIP codes

Weldon Spring city is a mid-size town in Missouri, with 5,291 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #140 of 1,082 ranked by population — larger than 87% of them. The median age here is 53.5 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 Weldon Spring city earn a median of $155,081 a year, 97.5% above the national figure of $78,538 and 179% 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 0.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Weldon Spring city is valued at $523,300, 72.5% above the national figure and 243% above the $152,400 peer median, while median gross rent runs $2,692 a month, 91.5% above the national figure, or roughly $32,304 across a full year. A household on the local median income would put about 20.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 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. 85.9% 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.

A median age of 53.5 puts Weldon Spring 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.
