Industrial-pollution burden
in the bottom 4.3% nationally
Lower is healthier
ST5thUS4thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Dry extreme heat
82.5 days/year
in the top 4.6% nationally
Lower is healthier
ST53rdUS95thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Arsenic in groundwater

in the bottom 5.3% nationally
Lower is healthier
ST4thUS5thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Humid extreme heat
140.6 days/year
in the top 7.2% nationally

ST61stUS93rdDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›High cholesterol

in the top 6.8% nationally
Lower is healthier
ST95thUS93rdDefinition & source ›
The estimated share of adults with high cholesterol, among those who have ever been screened for it.
Full methodology ›Fiber broadband

Higher is healthier
ST94thUS88thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Radon
0.8 pCi/L
in the bottom 7.6% nationally
Lower is healthier
ST43rdUS8thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Distance to a hazardous-chemical facility
10.5 mi
in the top 13.2% nationally
Higher is healthier
ST94thUS87thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›Coronary heart disease

in the top 13.3% nationally
Lower is healthier
ST90thUS87thDefinition & source ›
The estimated share of adults who have been told by a health professional that they have coronary heart disease or angina.
Full methodology ›The read
Bandera, Texas (ZIP 78003), on the composite measure, lands in the bottom 33% nationally (21,619th) and the top 47% of Texas (883rd).
The readings split fairly evenly between strengths and concerns: modeled industrial-pollution burden sits in the bottom 4.3% nationally, modeled arsenic registers in the bottom 5.3% nationally, and fiber broadband lands in the top 12.3% nationally. Modeled radon resides in the bottom 7.6% nationally, and distance to a hazardous-chemical facility lies in the top 13.2% nationally. Working the other way, modeled extreme heat settles in the top 4.6% nationally, and humid heat stands in the top 7.2% nationally. Modeled high cholesterol is in the top 6.8% nationally, and crowded housing rests in the top 10.7% nationally. Distance to a community health center sits in the top 13.0% nationally.
In everyday language, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. A healthier neighbor overall sits at ZIP 78010, 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 1.36 years of 81.0, 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.
