Knott, Texas (ZIP 79748), overall, ranks in the bottom 42% nationally (18,563rd) and the top 35% of Texas (658th), based on limited data; treat as directional.
Several serious readings shape the profile and deserve first mention: modeled nitrate resides in the top 0.06% nationally, modeled arsenic settles in the top 0.3% nationally, and walkability is in the bottom 2.9% nationally. Modeled extreme heat sits in the top 4.9% nationally, and uninsured lands in the top 8.3% nationally. On the better side, housing-cost burden lies at the national minimum, and home broadband subscription stands at the national maximum. Unemployment rests at the national minimum, shared with about 15% of ZIPs. Households without a vehicle registers at the national minimum, shared with about 16% of ZIPs. Modeled transportation noise resides in the bottom 8.6% nationally.
Measured against the nearby ZIPs, arsenic runs far higher than the surrounding ZIPs on this measure. Defined simply, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. ZIP 79738, about 9.2 miles away, comes out 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 1.97 years of 75.9, 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.
