Humid extreme heat
151.4 days/year
in the top 4.4% nationally
Lower is healthier
ST74thUS96thDefinition & 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 ›Fatal road crashes
44.8 per 100,000 residents per year
in the top 5.3% nationally
Lower is healthier
ST89thUS95thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Dry extreme heat
70.9 days/year
in the top 5.8% nationally
Lower is healthier
ST42ndUS94thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Distance to a Superfund site

Higher is healthier
ST7thUS10thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Radon
0.8 pCi/L
in the bottom 5.9% nationally
Lower is healthier
ST35thUS6thDefinition & 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 ›The read
Overall, Chappell Hill, Texas (ZIP 77426) lands in the bottom 50% nationally (16,130th) and the top 28% of Texas (529th).
The picture here is genuinely mixed, with readings on both sides: modeled radon settles in the bottom 5.9% nationally. Crowded housing resides at the national minimum, shared with about 29% of ZIPs. On the other side, modeled humid heat registers in the top 4.4% nationally, fatal road crashes rests in the top 5.3% nationally, and modeled extreme heat stands in the top 5.8% nationally. Distance to a Superfund site lies in the bottom 9.9% nationally, and floodplain exposure lands in the top 10.4% nationally. Distance to a hazardous-chemical facility sits at the national minimum, shared with about 31% of ZIPs. Unemployment is in the top 16% nationally. Recreation settles at the national minimum, shared with about 35% of ZIPs.
A note on the terms: distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. For a healthier nearby comparison, ZIP 77833, 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 1.16 years of 79.6, 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.
