Fenton, MO population, income and ZIP codes

Fenton city is a small town in Missouri, with 4,087 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #176 of 1,082 ranked by population — larger than 83% of them. The median age here is 47 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Fenton city earn a median of $97,991 a year, 24.8% above the national figure of $78,538 and 76% 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 3.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Fenton city is valued at $362,800, 19.6% above the national figure and 138% above the $152,400 peer median, while median gross rent runs $1,581 a month, 12.4% above the national figure, or roughly $18,972 across a full year. A household on the local median income would put about 19.4% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 87% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
