Overall, Liberty Hill, Texas (ZIP 78642) lands in the top 16% healthiest ZIPs nationally (4,990th) and the top 8.2% of Texas (153rd).
The measures that set this area apart are worth putting up front: household income is in the top 6.4% nationally, and modeled arsenic settles in the bottom 7.2% nationally. Modeled energy burden resides in the bottom 4.9% nationally, and coronary heart disease registers in the bottom 7.0% nationally. Modeled stroke rests in the bottom 6.7% nationally, modeled industrial-pollution burden stands in the bottom 10.9% nationally, and poverty lies in the bottom 10.9% nationally. Modeled hearing disability lands in the bottom 10.0% nationally. Set against that, modeled extreme heat sits in the top 4.0% nationally, and crowded housing is in the top 10.8% nationally.
Set beside the nearby areas, park land runs far lower than the surrounding ZIPs on this measure. A note on the terms: arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. For a healthier nearby comparison, ZIP 78628, just across the boundary, ranks better 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 0.99 years of 80.5, 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.
