Marrero, LA population, income and ZIP codes

Marrero CDP is a small city in Louisiana, with 31,866 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #13 of 489 ranked by population — larger than 97% of them. The median age here is 41.1 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 Marrero CDP earn a median of $45,633 a year, 41.9% below the national figure of $78,538 and 15% below the $53,775 median for the 268 Louisiana cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 22.2% 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 Marrero CDP is valued at $173,200, 42.9% below the national figure and within a couple of points of the $173,000 peer median, while median gross rent runs $997 a month, 29.1% below the national figure, or roughly $11,964 across a full year. A household on the local median income would put about 26.2% 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 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 67.1% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
