What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Child-care access
0.75 per 1,000 residents
in the top 4.6% nationally
Higher is healthier
ST97thUS95thDefinition & source ›
The number of child day-care services inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Loud transportation noise
2.2%
in the top 6.5% nationally
Lower is healthier
ST94thUS94thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›PFOA in drinking water
87.4%
in the top 9.7% nationally
Lower is healthier
ST92ndUS90thDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Radon
2.9 pCi/L
in the top 12.6% nationally
Lower is healthier
ST98thUS87thDefinition & 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 ›Walkability
86 intersections/sq mi
in the top 12.6% nationally
Higher is healthier
ST95thUS87thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Colon-cancer screening
72.2%
in the top 9.9% nationally
Higher is healthier
ST98thUS90thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Dental provider access
0.66 per 1,000 residents
in the top 15% nationally
Higher is healthier
ST91stUS85thDefinition & source ›
The number of dental offices located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Energy-cost burden
2.1%
in the bottom 15% nationally
Lower is healthier
ST5thUS15thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Fatal road crashes
4.5 per 100,000 residents per year
in the bottom 17% nationally
Lower is healthier
ST7thUS17thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Civic-institution access
0.37 per 1,000 residents
in the top 18% nationally
Higher is healthier
ST90thUS82ndDefinition & source ›
The number of civic and social organizations inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›The read
From the partial coverage available here, Lyndon, Kentucky (ZIP 40242) lands in the top 28% healthiest ZIPs nationally (8,912th) and the top 4.9% of Kentucky (36th), based on limited data; treat as directional.
The readings that are available are worth naming, coverage aside: childcare stands in the top 4.6% nationally. Distance to an emergency room sits at the national minimum, shared with about 11% of ZIPs. Mental-health providers resides in the top 11.6% nationally, walkability stands in the top 12.6% nationally, and modeled colon screening sits in the top 9.9% nationally. Dental providers resides in the top 15% nationally, and modeled energy burden stands in the bottom 15% nationally. On the other hand, modeled loud transportation noise sits in the top 6.5% nationally, PFOA in drinking water resides in the top 9.7% nationally, and modeled radon stands in the top 12.6% nationally.
Set beside the wider area around it, park land runs far lower than the surrounding ZIPs on this measure. For clarity, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. ZIP 40222, 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 81.5, 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.
