St. Joseph, LA population, income and ZIP codes

St. Joseph town is a very small community in Louisiana, with 709 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #312 of 489 ranked by population — larger than 36% of them. The median age here is 49 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 St. Joseph town earn a median of $33,864 a year, 56.9% below the national figure of $78,538 and 37% below the $53,775 median for the 268 Louisiana cities we cover. 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 41.3% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in St. Joseph town is valued at $56,100, 81.5% below the national figure and 68% below the $173,000 peer median, while median gross rent runs $746 a month, 46.9% below the national figure, or roughly $8,952 across a full year. A household on the local median income would put about 26.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 1.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 63.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 709 residents, a handful of survey responses moves every median on this page. Compare St. Joseph town against its county rather than against national figures.

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.
