Full methodology ›The read
Overall, Blackfoot, Idaho (ZIP 83221) places in the bottom 41% nationally (19,013th) and the bottom 32% of Idaho (182nd), based on limited data; treat as directional.
The measures land in both directions, and neither dominates: distance to an emergency room is at the national minimum, shared with about 11% of ZIPs. Modeled air-toxics cancer risk lands in the bottom 7.8% nationally, and humid heat stands in the bottom 10.3% nationally. Distance to a community health center registers at the national minimum, shared with about 23% of ZIPs. Pulling the other way, modeled mammography settles in the bottom 4.1% nationally, disaster risk sits in the top 3.4% nationally, and nitrate lies in the top 5.8% nationally. Modeled expected annual loss rests in the top 6.6% nationally, modeled fine-particle resides in the top 7.6% nationally, and walkability is in the bottom 8.8% nationally.
Beside the areas that surround it, expected annual loss runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, 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. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Among nearby ZIPs, the nearest healthier one overall is ZIP 83202, 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 0.62 years of 77.5, 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.
