This area's measures are easy to read as a mixed set: modeled radon registers in the bottom 14.5% nationally. Outer-floodplain exposure resides at the national minimum, shared with about 36% of ZIPs. Set against that, modeled humid heat settles in the top 6.0% nationally, and fatal road crashes is in the top 11.3% nationally.

Put simply, 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. 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. On the overall standing, ZIP 70722, about 20 miles away, ranks healthier.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.58 years of 75.3, and it’s very unlikely to be off by more than twice that.

Statistically similar ZIPs nationally

Similar means a ZIP whose health profile is shaped like this one’s — the same pattern of strengths and weaknesses across the nine health domains behind the Score, not similar demographics or income. The percentage is how closely the two patterns line up. A very similar ZIP can still have a different overall Score.

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.
