What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Humid extreme heat
156.6 days/year
in the top 3.1% nationally
Lower is healthier
ST89thUS97thDefinition & 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 ›Floodplain exposure
43.4%
in the top 5.4% nationally
Lower is healthier
ST93rdUS95thDefinition & 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 ›Short sleep
42.7%
in the top 7.2% nationally
Lower is healthier
ST92ndUS93rdDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Radon
0.7 pCi/L
in the bottom 3.4% nationally
Lower is healthier
ST23rdUS3rdDefinition & 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 ›Elder-services access
0.13 per 1,000 residents
in the top 12.1% nationally
Higher is healthier
ST91stUS88thDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Dry extreme heat
15 days/year
in the top 28% nationally
Lower is healthier
ST3rdUS72ndDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›Fine-particle (PM2.5) exceedance
0.18%
in the top 44% nationally
Lower is healthier
ST98thUS56thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.

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
Judged by its overall standing, Sweeny, Texas (ZIP 77480) sits in the bottom 28% nationally (22,943rd) and the bottom 45% of Texas (1,035th).
A balanced showing across the data, with a few readings each side: distance to an emergency room rests at the national minimum, shared with about 11% of ZIPs. Modeled radon settles in the bottom 3.4% nationally, and elder services lands in the top 12.1% nationally. Distance to a nursing home rests at the national minimum, shared with about 27% of ZIPs. On the other hand, modeled humid heat settles in the top 3.1% nationally, and floodplain exposure lands in the top 5.4% nationally. Modeled short sleep rests in the top 7.2% nationally, and industrial-pollution burden settles in the top 10.5% nationally. Outer-floodplain exposure lands in the top 10.6% nationally, and modeled uninsured rests in the top 10.7% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. A healthier nearby ZIP overall is ZIP 77420, 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 1.05 years of 76.2, 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
