Jefferson Parish, LA in context

How this area compares with national benchmarks.

Jefferson Parish is a mid-size city in Louisiana, with 432,484 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39.9 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Jefferson Parish earn a median of $65,246 a year, 16.9% 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 16.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Jefferson Parish is valued at $243,500, 19.7% below the national figure, while median gross rent runs $1,162 a month, 17.4% below the national figure, or roughly $13,944 across a full year. A household on the local median income would put about 21.4% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

How to read this page

What these estimates cover.

Figures are five-year rolling averages from the American Community Survey, not single-year counts, so they describe conditions across 2019-2023 ACS 5-year rather than a single date. Median home value covers owner-occupied units as valued by their owners, and median gross rent includes utilities the renter pays. Small counties carry wide margins of error; treat single-dollar differences between neighbouring counties as noise.
