Air-toxics cancer risk
45.3 per million
in the top 1.4% nationally
Lower is healthier
ST98thUS99thDefinition & 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 ›Outer-floodplain exposure
24.3%
in the top 1.7% nationally
Lower is healthier
ST98thUS98thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Floodplain exposure
55.7%
in the top 3.1% nationally
Lower is healthier
ST96thUS97thDefinition & 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 ›Humid extreme heat
152 days/year
in the top 4.2% nationally
Lower is healthier
ST76thUS96thDefinition & 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 ›Industrial-pollution burden
in the top 5.7% nationally
Lower is healthier
ST88thUS94thDefinition & 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 ›Crowded housing
8.6%
in the top 5.9% nationally
Lower is healthier
ST89thUS94thDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.
Full methodology ›Recreation access
1 per 1,000 residents
in the top 8.9% nationally
Higher is healthier
ST94thUS91stDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Radon
0.6 pCi/L
in the bottom 1.9% nationally
Lower is healthier
ST14thUS2ndDefinition & 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 ›Transportation noise
8.8%
in the top 10.5% nationally
Lower is healthier
ST91stUS90thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›PFAS in drinking water
45.2%
in the top 17% nationally
Lower is healthier
ST90thUS83rdDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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.

The read
Danbury, Texas (ZIP 77534), on the composite measure, lands in the bottom 35% nationally (20,858th) and the top 44% of Texas (817th).
Where this area is stretched, the data is unambiguous: modeled air-toxics cancer risk is in the top 1.4% nationally, outer-floodplain exposure rests in the top 1.7% nationally, and floodplain exposure sits in the top 3.1% nationally. Modeled humid heat registers in the top 4.2% nationally, modeled industrial-pollution burden lands in the top 5.7% nationally, and crowded housing resides in the top 5.9% nationally. Modeled transportation noise lies in the top 10.5% nationally, and short sleep settles in the top 10.5% nationally. Better still, recreation stands in the top 8.9% nationally, and modeled radon is in the bottom 1.9% nationally.
Set against the neighboring ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In everyday language, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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 77515, 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 0.92 years of 76.6, 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. How distance is measured
