Humid extreme heat
159.2 days/year
in the top 2.8% nationally
Lower is healthier
ST92ndUS97thDefinition & 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
55.5%
in the top 3.2% 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 ›Uninsured (under 65)
18.7%
in the top 5.7% nationally
Lower is healthier
ST62ndUS94thDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.
Full methodology ›Arsenic in groundwater
22.9%
in the top 5.2% nationally
Lower is healthier
ST92ndUS95thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
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.
Full methodology ›Diabetes
17.9%
in the top 8.4% nationally
Lower is healthier
ST86thUS92ndDefinition & source ›
The estimated share of adults who have been diagnosed with diabetes.
Full methodology ›Radon
0.7 pCi/L
in the bottom 3.9% nationally
Lower is healthier
ST26thUS4thDefinition & 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 ›Homeownership rate
93.3%
in the top 11.2% nationally
Higher is healthier
ST91stUS89thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.

The read
By the composite measure, Bayside, Texas (ZIP 78340) sits in the bottom 21% nationally (25,481st) and the bottom 29% of Texas (1,325th).
The readings split fairly evenly between strengths and concerns: modeled loud transportation noise registers at the national minimum, shared with about 22% of ZIPs. Modeled radon lands in the bottom 3.9% nationally, and homeownership resides in the top 11.2% nationally. Working the other way, modeled humid heat lies in the top 2.8% nationally, and floodplain exposure settles in the top 3.2% nationally. Modeled uninsured stands in the top 5.7% nationally, and arsenic is in the top 5.2% nationally. Modeled diabetes rests in the top 8.4% nationally. Fiber broadband sits at the national minimum, shared with about 19% of ZIPs. Households without a vehicle registers in the top 11.3% nationally.
Compared with the ZIPs that surround it, industrial-pollution burden runs far lower than the surrounding ZIPs on this measure. In plain language, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. ZIP 78382, 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 1.28 years of 80.7, 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.
