Outer-floodplain exposure

Lower is healthier
ST78thUS99thDefinition & 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 overall standing, ZIP 85373, one of several in Sun City, Arizona comes out in the top 25% healthiest ZIPs nationally (8,152nd) and the top 29% of Arizona (115th).
The profile opens balanced, with readings on either hand: modeled utility shutoff stands in the bottom 1.6% nationally, housing insecurity lands in the bottom 1.9% nationally, and binge drinking is in the bottom 1.9% nationally. Lead in tap water resides at the national minimum. By contrast, outer-floodplain exposure rests in the top 0.5% nationally, and modeled extreme heat lies in the top 0.5% nationally. Modeled hearing disability sits in the top 1.2% nationally, and high cholesterol settles in the top 1.0% nationally. Modeled coronary heart disease registers in the top 4.3% nationally, and tree cover stands at the national minimum.
Relative to the ZIPs around it, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. In plain terms, 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". Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The nearest healthier ZIP overall is ZIP 85375, 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

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
