Fort Polk South, LA population, income and ZIP codes

Fort Polk South CDP is a mid-size town in Louisiana, with 8,056 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #71 of 489 ranked by population — larger than 85% of them. The median age here is 22.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Fort Polk South CDP earn a median of $62,790 a year, 20.1% below the national figure of $78,538 and 17% above 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 18% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Fort Polk South CDP is valued at not published, while median gross rent runs $1,175 a month, 16.4% below the national figure, or roughly $14,100 across a full year. A household on the local median income would put about 22.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 0% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

A median age of 22.9 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld home value for Fort Polk South 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.
