Port Sulphur, LA population, income and ZIP codes

Port Sulphur CDP is a small town in Louisiana, with 1,529 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #221 of 489 ranked by population — larger than 54% of them. The median age here is 34.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Port Sulphur CDP earn a median of $54,342 a year, 30.8% below the national figure of $78,538 and within a couple of points of the $53,775 median for the 268 Louisiana cities we cover. 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 10.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Port Sulphur CDP is valued at $87,300, 71.2% below the national figure and 50% below the $173,000 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.6×, 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. 90.4% 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.

The Census withheld gross rent for Port Sulphur CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
