Transportation noise

The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.

ST99thUS99thDefinition & 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.

The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were 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.

ST95thUS95thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Walkability
150 intersections/sq mi
in the top 5.4% nationally
Higher is healthier
ST98thUS95thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Child-care access

Higher is healthier
ST96thUS93rdDefinition & 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 ›The read
From the partial coverage available here, ZIP 40217, one of several in Louisville, Kentucky lands in the top 38% healthiest ZIPs nationally (12,263rd) and the top 6.9% of Kentucky (51st), based on limited data; treat as directional.
The available readings suggest a handful of things about this area: walkability is in the top 5.4% nationally, and childcare registers in the top 6.9% nationally. Physicians lies in the top 8.3% nationally, and civic is in the top 11.5% nationally. By contrast, modeled transportation noise registers in the top 0.6% nationally, PFOA in drinking water lies at the national maximum, and modeled loud transportation noise is in the top 2.4% nationally. Modeled air-toxics cancer risk registers in the top 4.5% nationally, PFAS in drinking water lies at the national maximum, and modeled industrial-pollution burden is in the top 5.2% nationally.
Set beside the wider area around it, transportation noise runs far higher 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 40204, 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 0.82 years of 74.4, 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.
