Topock, Arizona (ZIP 86436), by its overall standing, sits in the bottom 29% nationally (22,775th) and the bottom 32% of Arizona (266th).
The data is direct about where this area carries real strain: modeled extreme heat is in the top 0.5% nationally, mammography resides in the bottom 2.0% nationally, and hearing disability rests in the top 3.5% nationally. Modeled coronary heart disease lies in the top 5.1% nationally, modeled high cholesterol sits in the top 4.2% nationally, and lithium in drinking water settles in the top 6.6% nationally. Modeled stroke registers in the top 6.9% nationally. More encouragingly, fiber broadband stands in the top 2.1% nationally, and distance to a Superfund site lands in the top 2.8% nationally. Modeled industrial-pollution burden is in the bottom 4.0% nationally.
Defined in plain terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. The nearest ZIP ranking healthier overall is ZIP 86404, 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 1.02 years of 74.3, 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.
