Dry extreme heat
129.8 days/year

Lower is healthier
ST70thUS99thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Lithium in drinking water
180 µg/L
in the top 0.7% nationally
Lower is healthier
ST90thUS99thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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.
Full methodology ›Outer-floodplain exposure

in the top 4.4% nationally
Lower is healthier
ST65thUS96thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.

Lower is healthier
ST9thUS15thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›The read
ZIP 85138, one of several in Maricopa, Arizona, overall, ranks in the top 45% healthiest ZIPs nationally (14,567th) and the top 46% of Arizona (181st).
This area's measures are easy to read as a mixed set: home broadband subscription resides in the top 8.0% nationally, and lead in tap water settles in the bottom 10.1% nationally. Distance to a community health center is at the national minimum, shared with about 23% of ZIPs. Fatal road crashes sits in the bottom 14.8% nationally. Set against that, modeled extreme heat lands in the top 0.5% nationally, and lithium in drinking water lies in the top 0.7% nationally. Outer-floodplain exposure stands in the top 4.4% nationally, and modeled tree cover rests at the national minimum. Modeled humid heat registers in the top 6.8% nationally. Distance to a hazardous-chemical facility resides at the national minimum, shared with about 31% of ZIPs.
Measured against the nearby ZIPs, park land runs far lower than the surrounding ZIPs on this measure. Defined simply, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. ZIP 85339, just across the boundary, comes out 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 1.01 years of 79.3, 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.
