Humid extreme heat
155 days/year
in the top 3.4% nationally
Lower is healthier
ST85thUS97thDefinition & 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
48.1 per 100,000 residents per year
in the top 4.4% nationally
Lower is healthier
ST91stUS96thDefinition & 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 ›Floodplain exposure
40.9%
in the top 6.0% nationally
Lower is healthier
ST92ndUS94thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Unemployment rate
11.1%
in the top 7.7% nationally
Lower is healthier
ST94thUS92ndDefinition & source ›
The share of the civilian labor force that is unemployed.
Full methodology ›Air-toxics cancer risk

Lower is healthier
ST83rdUS91stDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›Radon
0.7 pCi/L
in the bottom 2.3% nationally
Lower is healthier
ST16thUS2ndDefinition & 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 ›Dry extreme heat
27.2 days/year

The average number of days per year with a modeled daily high of at least 95 °F.

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.
This area ranks among the highest 10% of US ZIP codes for both humid-heat days and flood exposure.

The read
By the composite health measure, Damon, Texas (ZIP 77430) ranks in the bottom 41% nationally (18,923rd) and the top 37% of Texas (684th).
The picture here is genuinely mixed, with readings on both sides: modeled radon lands in the bottom 2.3% nationally, and transportation noise sits in the bottom 17% nationally. Modeled arsenic is in the bottom 17% nationally. On the other side, modeled humid heat settles in the top 3.4% nationally, fatal road crashes resides in the top 4.4% nationally, and floodplain exposure registers in the top 6.0% nationally. Unemployment rests in the top 7.7% nationally, modeled air-toxics cancer risk stands in the top 9.1% nationally, and modeled mammography lies in the bottom 11.7% nationally. Modeled extreme heat lands in the top 17% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Close by, ZIP 77461, just across the boundary, ranks 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 1.07 years of 78.3, 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.
