Full methodology ›The read
ZIP 83686, one of several in Nampa, Idaho, by its overall standing, sits in the top 38% healthiest ZIPs nationally (12,100th) and the top 37% of Idaho (98th).
The profile opens balanced, with readings on either hand: floodplain exposure stands at the national minimum, subsidized affordable housing lands in the top 7.2% nationally, and modeled loneliness is in the bottom 9.0% nationally. Distance to a community health center resides at the national minimum, shared with about 23% of ZIPs. By contrast, modeled mammography rests in the bottom 3.0% nationally, and nitrate lies in the top 2.3% nationally. Modeled arsenic sits in the top 2.7% nationally, and disaster risk settles in the top 4.7% nationally. Modeled fine-particle registers in the top 5.2% nationally, and air-toxics cancer risk stands in the top 9.1% nationally.
Held up against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. The nearest ZIP ranking healthier overall is ZIP 83634, 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 0.38 years of 79.5, 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.
