Full methodology ›The read
By its overall health score, Bedias, Texas (ZIP 77831) lands in the bottom 43% nationally (18,384th) and the top 35% of Texas (646th).
The measures split the difference for this area: modeled pfas is in the bottom 3.1% nationally, and radon stands in the bottom 12.3% nationally. Homeownership settles in the top 16% nationally. Against that, modeled humid heat lies in the top 5.5% nationally, modeled extreme heat resides in the top 5.6% nationally, and poverty lands in the top 7.2% nationally. Households without a vehicle registers in the top 8.3% nationally, crowded housing sits in the top 8.6% nationally, and walkability rests in the bottom 10.6% nationally. Home broadband subscription is in the bottom 15% nationally.
To translate a couple of terms, 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Overall, the nearest healthier neighbor is ZIP 77830, 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 0.98 years of 77.8, 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.
