Livingston Parish · Baton Rouge, LA · Population 12,483
Livingston, LA (ZIP 70754) sits in Livingston Parish within the Baton Rouge metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Depression comes in above the national average at 31.3%. NCES lists 3 schools serving the area, 3 non-charter. 3 colleges and universities serve the area, with median in-state tuition of $4,079. IRS data shows average household income (AGI) of $68,132, well above the ~$45K national average per return. BLS QCEW reports average annual pay of $46,193 per worker, roughly 29% below the US average. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. FEMA has issued 52 federal disaster declarations affecting this ZIP since 1965 — a high-frequency exposure profile. Annual precipitation averages 63.8" — a wet-climate ZCTA per NOAA's 1991–2020 Normals. County Health Rankings reports 11,382 years of potential life lost per 100,000 (2025) — well above the national county median. 28.1% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Louisiana levies a flat state income tax (top rate 3.00%); a household at the local median AGI of $68,132 would pay roughly $1,226/year before deductions. New residents arriving here predominantly come from East Baton Rouge Parish, LA (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $65,964, fair market rent of $1,280 for a two-bedroom, and a typical home value of $252,823, up 2.4% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

Livingston, LA (ZIP 70754) sits in Livingston Parish within the Baton Rouge metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Depression comes in above the national average at 31.3%. NCES lists 3 schools serving the area, 3 non-charter. 3 colleges and universities serve the area, with median in-state tuition of $4,079. IRS data shows average household income (AGI) of $68,132, well above the ~$45K national average per return. BLS QCEW reports average annual pay of $46,193 per worker, roughly 29% below the US average. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. FEMA has issued 52 federal disaster declarations affecting this ZIP since 1965 — a high-frequency exposure profile. Annual precipitation averages 63.8" — a wet-climate ZCTA per NOAA's 1991–2020 Normals. County Health Rankings reports 11,382 years of potential life lost per 100,000 (2025) — well above the national county median. 28.1% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Louisiana levies a flat state income tax (top rate 3.00%); a household at the local median AGI of $68,132 would pay roughly $1,226/year before deductions. New residents arriving here predominantly come from East Baton Rouge Parish, LA (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $65,964, fair market rent of $1,280 for a two-bedroom, and a typical home value of $252,823, up 2.4% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 31.3%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
