Outer-floodplain exposure

ST83rdUS99thDefinition & 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.

Full methodology ›The read
In its overall standing, Litchfield Park, Arizona (ZIP 85340) lands in the top 17% healthiest ZIPs nationally (5,343rd) and the top 20% of Arizona (77th).
Taken together, the data gives a genuinely mixed reading: lead in tap water is at the national minimum, home broadband subscription sits in the top 8.6% nationally, and household income lands in the top 8.9% nationally. Modeled coronary heart disease lies in the bottom 9.7% nationally, dental providers stands in the top 12.7% nationally, and modeled high blood pressure rests in the bottom 10.4% nationally. On the other side, outer-floodplain exposure registers in the top 0.4% nationally, and modeled extreme heat resides in the top 0.5% nationally. Lithium in drinking water settles in the top 4.2% nationally, and modeled tree cover is at the national minimum.
Against the wider neighborhood, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Put 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". On the overall standing, ZIP 85309, just across the boundary, ranks healthier.

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 0.76 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. How distance is measured
