The read
In overall standing, Napoleonville, Louisiana (ZIP 70390) comes out in the bottom 6.3% nationally (30,077th) and the bottom 23% of Louisiana (389th).
The profile opens on the burdens that define it most: modeled air-toxics cancer risk is in the top 1.6% nationally, floodplain exposure resides in the top 2.1% nationally, and modeled tooth loss rests in the top 5.2% nationally. Modeled industrial-pollution burden lies in the top 3.6% nationally, humid heat sits in the top 4.0% nationally, and self-care disability settles in the top 6.3% nationally. Modeled cognitive disability registers in the top 5.8% nationally, and diabetes stands in the top 6.5% nationally. Modeled fair or poor health lands in the top 7.5% nationally. More positively, distance to an emergency room is at the national minimum, shared with about 11% of ZIPs.
Relative to the ZIPs around it, industrial-pollution burden runs far lower than the surrounding ZIPs on this measure. In plain terms, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". The nearest healthier ZIP overall is ZIP 70301, just across the boundary.

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 1.58 years of 76.7, 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
