The read

On balance, and by the composite measure, Lyndon, Kansas (ZIP 66451) ranks in the top 46% healthiest ZIPs nationally (14,895th) and the top 39% of Kansas (264th).

Taken together, the profile's clearest strengths surface right away: unemployment sits at the national minimum, shared with about 15% of ZIPs. Modeled loneliness rests in the bottom 11.6% nationally, and short sleep is in the bottom 13.0% nationally. Distance to a Superfund site stands in the top 16% nationally. Against that, distance to an emergency room settles in the top 5.3% nationally. Fiber broadband lies at the national minimum, shared with about 19% of ZIPs. Distance to a community health center resides in the top 12.2% nationally, modeled extreme heat lands in the top 14.7% nationally, and lead in tap water registers in the top 14.8% nationally. Floodplain exposure sits in the top 14.8% nationally.

In plainer terms, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay.

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 1.70 years of 80.3, 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.
