ST83rdUS93rdDefinition & 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)

ST55thUS93rdDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.
Full methodology ›Radon
0.8 pCi/L

Lower is healthier
ST39thUS7thDefinition & 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 ›Distance to a hazardous-chemical facility
8.4 mi

Higher is healthier
ST90thUS83rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›The read
Overall, Castroville, Texas (ZIP 78009) lands in the top 40% healthiest ZIPs nationally (12,955th) and the top 21% of Texas (398th).
The signals balance out across the profile, strengths against concerns: modeled radon stands in the bottom 6.8% nationally, and dental providers lies in the top 14.4% nationally. Poverty lands in the bottom 15% nationally, and modeled energy burden sits in the bottom 14.4% nationally. Distance to a hazardous-chemical facility is in the top 17% nationally, and childcare settles in the top 21% nationally. Set against that, modeled extreme heat resides in the top 1.4% nationally, modeled humid heat registers in the top 4.3% nationally, and outer-floodplain exposure rests in the top 7.0% nationally. Modeled uninsured stands in the top 7.5% nationally.
Set beside the nearby areas, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. A note on the terms: radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. 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. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier nearby comparison, ZIP 78056, just across the boundary, ranks better 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 1.30 years of 82.6, 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.
