The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.

ST7thUS13thDefinition & 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 ›The read
On the composite measure, Clyo, Georgia (ZIP 31303) stands in the bottom 47% nationally (16,975th) and the top 40% of Georgia (285th).
A balanced set of signals defines this area, not any single one: unemployment resides at the national minimum, shared with about 15% of ZIPs. Modeled pfas stands in the bottom 14.2% nationally, and radon sits in the bottom 12.6% nationally. Modeled arsenic resides in the bottom 17% nationally. Outer-floodplain exposure stands at the national minimum, shared with about 36% of ZIPs. By contrast, modeled humid heat sits in the top 7.0% nationally, crowded housing resides in the top 7.1% nationally, and walkability stands in the bottom 12.7% nationally. Distance to a hazardous-chemical facility sits at the national minimum, shared with about 31% of ZIPs. Home broadband subscription resides in the bottom 18% nationally.
For clarity, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. 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. ZIP 31329, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.90 years of 75.4, 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.
