Full methodology ›The read
Judged by its overall standing, ZIP 96821, one of several in Honolulu, Hawaii sits in the top 0.8% healthiest ZIPs nationally (252nd) and the top 2.2% of Hawaii (2nd), based on limited data; treat as directional.
An even profile, with readings pulling both ways: household income resides in the top 2.0% nationally, modeled utility shutoff sits in the bottom 0.5% nationally, and modeled obesity stands in the bottom 1.2% nationally. Modeled transportation resides in the bottom 2.2% nationally, housing insecurity sits in the bottom 2.4% nationally, and air-toxics cancer risk stands in the bottom 2.8% nationally. Modeled cognitive disability resides in the bottom 1.1% nationally, and lead in tap water sits at the national minimum. Modeled independent living disability stands in the bottom 2.3% nationally. Against that, modeled disaster risk resides in the top 2.1% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. A healthier nearby ZIP overall is ZIP 96825, 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 83.5, 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. How distance is measured
