Old Jefferson CDP, LA in context
How this area compares with national benchmarks.
Old Jefferson CDP is a mid-size town in Louisiana, with 7,790 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #73 of 489 ranked by population — larger than 85% of them. The median age here is 37.4 years against 39.1 nationally, a slightly younger 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 Old Jefferson CDP earn a median of $85,466 a year, 8.8% above the national figure of $78,538 and 59% above the $53,775 median for the 268 Louisiana cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8.9% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Old Jefferson CDP is valued at $235,900, 22.2% below the national figure and 36% above the $173,000 peer median, while median gross rent runs $1,174 a month, 16.5% below the national figure, or roughly $14,088 across a full year. A household on the local median income would put about 16.5% 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. 74.6% 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.
