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.
Dental provider access
1.2 per 1,000 residents
in the top 4.0% nationally
Higher is healthier
ST97thUS96thDefinition & 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 ›PFOA in drinking water
98.5%
in the top 4.5% nationally
Lower is healthier
ST95thUS96thDefinition & 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 ›Physician access

The number of physicians’ 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.

ST97thUS92ndDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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.

Lower is healthier
ST3rdUS10thDefinition & 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 ›The read
On what the available sources can show, ZIP 40223, one of several in Louisville, Kentucky lands in the top 8.6% healthiest ZIPs nationally (2,757th) and the top 1.3% of Kentucky (9th), based on limited data; treat as directional.
From the measures that are available, a few readings can be named: dental providers rests in the top 4.0% nationally, and physicians stands in the top 5.5% nationally. Recreation lies in the top 7.6% nationally, and modeled colon screening lands in the top 5.5% nationally. Outpatient sits in the top 10.3% nationally, and childcare is in the top 11.9% nationally. On the other side, PFOA in drinking water settles in the top 4.5% nationally, modeled loud transportation noise resides in the top 7.6% nationally, and modeled expected annual loss registers in the top 10.6% nationally. PFAS in drinking water rests in the top 11.8% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Close by, ZIP 40241, just across the boundary, ranks healthier overall.

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 0.67 years of 82.1, 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.
