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

St. Martin Parish is a small city in Louisiana, with 51,559 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39.7 years against 39.1 nationally, a slightly older 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. Martin Parish earn a median of $53,394 a year, 32% 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 16.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in St. Martin Parish is valued at $151,000, 50.2% below the national figure, while median gross rent runs $865 a month, 38.5% below the national figure, or roughly $10,380 across a full year. A household on the local median income would put about 19.4% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 78.9% 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.

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.
