Full methodology ›The read
By the composite health measure, Grandfalls, Texas (ZIP 79742) ranks in the bottom 20% nationally (25,497th) and the bottom 29% of Texas (1,326th), based on limited data; treat as directional.
Where the load on this area runs deepest, the data leads: modeled uninsured resides in the top 2.9% nationally, and extreme heat registers in the top 1.2% nationally. Crowded housing rests in the top 4.5% nationally, and modeled tree cover stands at the national minimum. Distance to a community health center lies in the top 5.3% nationally. Fiber broadband lands at the national minimum, shared with about 19% of ZIPs. Slow internet speeds sits in the top 10.7% nationally, walkability is in the bottom 11.4% nationally, and modeled pfas settles in the top 12.7% nationally. More encouragingly, modeled loud transportation noise resides at the national minimum, shared with about 22% of ZIPs.
To spell things out, 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. Close by, ZIP 79756, just across the boundary, ranks healthier overall.

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 1.50 years of 79.1, 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.
