By the composite measure, ZIP 83687, one of several in Nampa, Idaho sits in the bottom 49% nationally (16,405th) and the bottom 44% of Idaho (151st).
Where this area is stretched, the data is unambiguous: modeled mammography is in the bottom 1.5% nationally, air-toxics cancer risk rests in the top 1.1% nationally, and nitrate sits in the top 1.6% nationally. Modeled fine-particle registers in the top 5.1% nationally, disaster risk lands in the top 8.9% nationally, and tree cover resides in the bottom 10.4% nationally. Modeled colon screening lies in the bottom 9.5% nationally. Better still, distance to an emergency room settles at the national minimum, shared with about 11% of ZIPs. Subsidized affordable housing stands in the top 9.1% nationally, and modeled high blood pressure is in the bottom 8.7% nationally.
Compared with the ZIPs that surround it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In plain language, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. ZIP 83634, just across the boundary, ranks 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 0.59 years of 79.0, 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
