Full methodology ›The read
Twin Falls, Idaho (ZIP 83301), in overall standing, comes out in the top 47% healthiest ZIPs nationally (15,186th) and the top 50% of Idaho (133rd), based on limited data; treat as directional.
A balanced showing across the data, with a few readings each side: modeled high cholesterol sits in the bottom 3.2% nationally, subsidized affordable housing stands in the top 4.5% nationally, and mental-health providers resides in the top 5.0% nationally. Distance to an emergency room sits at the national minimum, shared with about 11% of ZIPs. Distance to a Superfund site stands in the top 6.0% nationally, and physicians resides in the top 9.4% nationally. Dental providers sits in the top 10.8% nationally. On the other hand, modeled arsenic stands in the top 0.3% nationally, and disaster risk resides in the top 1.6% nationally. Modeled nitrate sits in the top 2.0% nationally.
Set within its surrounding area, arsenic runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. The closest healthier ZIP overall is ZIP 83328, 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 0.45 years of 77.6, 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.
