St. Charles ZIP codes — St. Charles Parish, Louisiana

St. Charles Parish is a small city in Louisiana, with 51,863 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39.1 years against 39.1 nationally, a slightly younger 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 St. Charles Parish earn a median of $82,172 a year, 4.6% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 9.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in St. Charles Parish is valued at $256,800, 15.4% below the national figure, while median gross rent runs $1,144 a month, 18.6% below the national figure, or roughly $13,728 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.7% 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.
