ZIP code 63376

ZIP 63376 is a small city in St. Charles County, Missouri, with 74,876 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 1,035 ranked by population. The median age here is 41 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in ZIP 63376 earn a median of $94,921 a year, 20.9% 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 4.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 63376 is valued at $255,500, 15.8% below the national figure, while median gross rent runs $1,319 a month, 6.2% below the national figure, or roughly $15,828 across a full year. A household on the local median income would put about 16.7% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.6% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.

ZIP 63376 is tabulated inside St. Charles County, Missouri, one of 14 ZIP areas the Census publishes for that county and 1,035 across Missouri. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. 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 63376 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 63376 reports a median household income of $94,921, 13% below the $109,155 county median, and 57% above the $60,651 typical MO ZIP.

Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,319 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 63376 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 63376 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.
