ST69thUS98thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Lead in tap water

Lower is healthier
US1stDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

ST78thUS92ndDefinition & source ›
The number of public-transit stops inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Crowded housing

The share of occupied homes with more than one person per room, the Census definition of crowded housing.

The number of services for older adults and people with disabilities inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
Overall, Waialua, Hawaii (ZIP 96791) lands in the top 22% healthiest ZIPs nationally (6,939th) and the top 50% of Hawaii (46th), based on limited data; treat as directional.
The picture here is genuinely mixed, with readings on both sides: lead in tap water is at the national minimum, and park land settles in the top 4.8% nationally. Modeled air-toxics cancer risk resides in the bottom 6.2% nationally, and transit registers in the top 7.7% nationally. Modeled obesity rests in the bottom 10.7% nationally, and distance to a hazardous-chemical facility stands in the top 9.4% nationally. On the other side, modeled short sleep lies in the top 0.6% nationally, modeled disaster risk lands in the top 2.4% nationally, and crowded housing sits in the top 8.3% nationally. Housing-cost burden is in the top 9.9% nationally.
Set beside the nearby areas, park land runs far higher than the surrounding ZIPs on this measure. A note on the 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. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. For a healthier nearby comparison, ZIP 96857, about 0.4 miles away, ranks better 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 1.13 years of 83.7, 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.
