On balance, and by the composite measure, Round Mountain, Texas (ZIP 78663) ranks in the top 27% healthiest ZIPs nationally (8,520th) and the top 13.8% of Texas (257th), based on limited data; treat as directional.
The measures split the difference for this area: household income is in the top 2.4% nationally, and modeled industrial-pollution burden stands in the bottom 6.3% nationally. Modeled energy burden settles in the bottom 3.8% nationally. Households without a vehicle lies at the national minimum, shared with about 16% of ZIPs. Modeled tooth loss resides in the bottom 3.8% nationally. Against that, slow internet speeds lands in the top 3.7% nationally, modeled extreme heat registers in the top 4.8% nationally, and modeled humid heat sits in the top 9.4% nationally. Walkability rests in the bottom 10.3% nationally, and distance to a community health center is in the top 11.4% nationally.
Compared with the ZIPs it borders, slow internet speeds runs far higher than the surrounding ZIPs on this measure. In plainer terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Energy burden is the share of household income that goes to home energy bills. For a healthier nearby ZIP overall, look to ZIP 78620, 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 1.13 years of 78.6, 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.
