A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.

Reading across the data, the real pressures come first: modeled uninsured lands in the top 1.7% nationally, homeownership lies at the national minimum, and modeled arsenic stands in the top 1.8% nationally. Modeled humid heat rests in the top 2.5% nationally, and extreme heat registers in the top 4.9% nationally. Fiber broadband resides at the national minimum, shared with about 19% of ZIPs. More encouragingly, poverty settles at the national minimum. Unemployment is at the national minimum, shared with about 15% of ZIPs. Households without a vehicle sits at the national minimum, shared with about 16% of ZIPs. Modeled radon lands in the bottom 2.0% nationally.

Against the wider neighborhood, arsenic runs far higher than the surrounding ZIPs on this measure. Put simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. On the overall standing, ZIP 78410, about 17 miles away, ranks healthier.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.38 years of 76.1, 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.
