Iola, Texas (ZIP 77861) ranks in the top 48% healthiest ZIPs nationally (15,453rd) and the top 27% of Texas (497th).
The bright spots in the data define much of the story here: modeled pfas lies in the bottom 4.7% nationally, and fiber broadband is in the top 13.6% nationally. Modeled radon registers in the bottom 10.5% nationally, and outpatient lies in the top 14.4% nationally. On the other side, modeled humid heat is in the top 4.2% nationally, modeled extreme heat registers in the top 5.1% nationally, and walkability lies in the bottom 10.9% nationally. Distance to a hazardous-chemical facility is at the national minimum, shared with about 31% of ZIPs. Floodplain exposure registers in the top 17% nationally, and fatal road crashes lies in the top 18% nationally.
For context, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. 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. The closest ZIP that ranks healthier overall is ZIP 77808, 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 1.12 years of 81.4, 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.
