St. John the Baptist Parish, LA in context

How this area compares with national benchmarks.

St. John the Baptist Parish is a small city in Louisiana, with 41,342 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 38.5 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. John the Baptist Parish earn a median of $67,418 a year, 14.2% below the national figure of $78,538. 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 12.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in St. John the Baptist Parish is valued at $184,000, 39.4% below the national figure, while median gross rent runs $1,118 a month, 20.5% below the national figure, or roughly $13,416 across a full year. A household on the local median income would put about 19.9% 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. 79.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

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.

How to read this page

What these estimates cover.

Figures are five-year rolling averages from the American Community Survey, not single-year counts, so they describe conditions across 2019-2023 ACS 5-year rather than a single date. Median home value covers owner-occupied units as valued by their owners, and median gross rent includes utilities the renter pays. Small counties carry wide margins of error; treat single-dollar differences between neighbouring counties as noise.
