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 ›The read
On balance, and by the composite measure, Lockhart, Texas (ZIP 78644) ranks in the bottom 35% nationally (20,717th) and the top 43% of Texas (808th).
The burdens that read clearest in the data come first: modeled uninsured lands in the top 2.9% nationally, and extreme heat registers in the top 2.4% nationally. Modeled humid heat sits in the top 5.8% nationally, and colon screening rests in the bottom 7.9% nationally. Modeled expected annual loss is in the top 9.7% nationally. Better still, modeled radon stands in the bottom 2.2% nationally. Distance to a community health center settles at the national minimum, shared with about 23% of ZIPs. Grocery lies in the top 12.4% nationally. Distance to a nursing home resides at the national minimum, shared with about 27% of ZIPs. Subsidized affordable housing lands in the top 14.8% nationally.
Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier nearby ZIP overall, look to ZIP 78610, 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 0.69 years of 77.9, 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.
