Taken together, the profile's clearest strengths surface right away: lithium in drinking water stands in the bottom 5.2% nationally, and modeled energy burden settles in the bottom 5.2% nationally. Modeled short sleep lies in the bottom 8.3% nationally, and cognitive disability resides in the bottom 10.8% nationally. Household income lands in the top 12.1% nationally, and modeled independent living disability registers in the bottom 13.3% nationally. Against that, modeled extreme heat sits in the top 2.9% nationally, modeled humid heat rests in the top 8.2% nationally, and floodplain exposure is in the top 12.3% nationally. Outer-floodplain exposure stands in the top 15% nationally.
Weighed against the ZIPs nearby, park land runs far lower than the surrounding ZIPs on this measure. To translate a couple of terms, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. 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 78641, 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 1.37 years of 81.3, 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.
