Floodplain exposure
75%
in the top 1.4% nationally
Lower is healthier
ST98thUS99thDefinition & 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
153.8 days/year
in the top 3.7% nationally
Lower is healthier
ST81stUS96thDefinition & 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 ›Short sleep

Lower is healthier
ST96thUS96thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.

Lower is healthier
ST87thUS95thDefinition & 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 ›Uninsured (under 65)
17.7%
in the top 6.8% nationally
Lower is healthier
ST58thUS93rdDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.
Full methodology ›Radon
0.6 pCi/L
in the bottom 1.0% nationally
Lower is healthier
ST8thUS1stDefinition & 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.

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
Brazoria, Texas (ZIP 77422), overall, ranks in the bottom 24% nationally (24,389th) and the bottom 36% of Texas (1,196th).
Taken together, the data gives a genuinely mixed reading: modeled radon rests in the bottom 1.0% nationally. On the other side, floodplain exposure registers in the top 1.4% nationally, modeled humid heat resides in the top 3.7% nationally, and modeled short sleep settles in the top 4.5% nationally. Outer-floodplain exposure is in the top 5.3% nationally, and modeled uninsured sits in the top 6.8% nationally. Modeled industrial-pollution burden lands in the top 10.2% nationally, and mammography lies in the bottom 10.4% nationally. Distance to a hazardous-chemical facility stands at the national minimum, shared with about 31% of ZIPs. Crowded housing rests in the top 17% nationally.
Measured against the nearby ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. ZIP 77480, just across the boundary, comes out 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 0.74 years of 76.5, 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.
