ZIP 63127 in context
How this area compares with national benchmarks.
ZIP 63127 is a mid-size town in St. Louis County, Missouri, with 5,161 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #282 of 1,035 ranked by population — larger than 72% of them. The median age here is 53.6 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 ZIP 63127 earn a median of $124,583 a year, 58.6% above the national figure of $78,538. 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 2.6% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 63127 is valued at $594,100, 95.8% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 4.8×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 78.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
A median age of 53.6 puts ZIP 63127 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.
The Census withheld gross rent for ZIP 63127 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
Reading ZIP 63127 in context
How 63127 sits inside St. Louis County and Missouri.
ZIP 63127 is tabulated inside St. Louis County, Missouri, one of 43 ZIP areas the Census publishes for that county and 1,035 across Missouri. Population sits in the small-town band, typically one main street plus the addresses that feed into it. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 63127 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 63127 reports a median household income of $124,583, 45% above the $86,196 county median, and 105% above the $60,651 typical MO ZIP. Owner-occupied homes are valued at a median of $594,100, 113% above the county figure and 267% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.
Missouri charges 4.225% statewide, and local governments overlapping 63127 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.
Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 63127 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
