What these numbers say together
Morrow, LA (ZIP 71356) sits in St. Landry Parish. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in above the national average at 50.6%. No NCES schools are mapped to this ZIP in the current dataset. 6 colleges and universities serve the area, with median in-state tuition of $7,050. 29% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. BLS QCEW reports average annual pay of $47,117 per worker, roughly 28% below the US average. FEMA has issued 53 federal disaster declarations affecting this ZIP since 1965 — a high-frequency exposure profile. Annual precipitation averages 61.6" — a wet-climate ZCTA per NOAA's 1991–2020 Normals. County Health Rankings reports 16,089 years of potential life lost per 100,000 (2025) — well above the national county median. Louisiana levies a flat state income tax (top rate 3.00%); a household at the local median AGI of $49,000 would pay roughly $882/year before deductions. IRS migration data (2022-2023) shows a net loss of 441 residents (303 households) — the ZIP's primary county is shrinking. 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 $25,625, fair market rent of $840 for a two-bedroom, and a median home value of $130,100. 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.
- Fair market rent for a two-bedroom ($840/month, HUD SAFMR) represents 39% of median household income ($25,625, Census ACS) — above the 30% affordability threshold commonly used by housing experts.
- Lower median household income ($25,625, Census ACS) sits alongside an above-average 39.9% obesity rate (CDC PLACES) — a pattern that correlates with reduced healthcare access in lower-income areas.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 26.7%. 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.

The Social Vulnerability Index uses U.S. Census data to identify communities most at risk during public health emergencies and natural disasters. Higher percentiles indicate greater vulnerability. Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.
