The read
Chalmette, Louisiana (ZIP 70043), overall, ranks in the bottom 11.4% nationally (28,414th) and the bottom 40% of Louisiana (303rd).
Reading across the data, the real pressures come first: outer-floodplain exposure lands in the top 1.1% nationally, floodplain exposure lies in the top 2.8% nationally, and modeled industrial-pollution burden stands in the top 3.9% nationally. Modeled cognitive disability rests in the top 5.5% nationally, humid heat registers in the top 4.8% nationally, and utility shutoff resides in the top 5.9% nationally. Modeled housing insecurity settles in the top 7.1% nationally, and food insecurity is in the top 7.5% nationally. Modeled transportation sits in the top 7.6% nationally. More encouragingly, distance to an emergency room lands at the national minimum, shared with about 11% of ZIPs.
Measured against the nearby ZIPs, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. Defined simply, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". ZIP 70032, just across the boundary, comes out healthier overall.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 0.70 years of 74.4, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match. How distance is measured
