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.
Loud transportation noise
2.9%
in the top 4.0% nationally
Lower is healthier
ST97thUS96thDefinition & 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 ›Dental provider access
1.2 per 1,000 residents
in the top 4.4% 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 ›Expected annual disaster loss
$0
in the top 6.9% nationally
Lower is healthier
ST93rdUS93rdDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›PFOA in drinking water
93.9%
in the top 7.0% nationally
Lower is healthier
ST94thUS93rdDefinition & 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 ›Transportation noise
9.6%
in the top 9.3% nationally
Lower is healthier
ST92ndUS91stDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Radon
2.8 pCi/L
in the top 13.2% nationally
Lower is healthier
ST97thUS87thDefinition & 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
91 intersections/sq mi
in the top 11.9% nationally
Higher is healthier
ST95thUS88thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Subsidized affordable housing
186 units
in the top 12.5% nationally
Higher is healthier
ST94thUS88thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Natural-disaster risk
in the top 14.3% nationally
Lower is healthier
ST92ndUS86thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Colon-cancer screening
71.7%
in the top 11.9% nationally
Higher is healthier
ST97thUS88thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›The read
From the partial coverage available here, ZIP 40220, one of several in Louisville, Kentucky lands in the top 29% healthiest ZIPs nationally (9,268th) and the top 5.3% of Kentucky (39th), based on limited data; treat as directional.
Several of the measures in hand are worth setting out: dental providers lies in the top 4.4% nationally, and walkability is in the top 11.9% nationally. Subsidized affordable housing registers in the top 12.5% nationally. Distance to a nursing home lies at the national minimum, shared with about 27% of ZIPs. On the other side, modeled loud transportation noise is in the top 4.0% nationally, modeled expected annual loss registers in the top 6.9% nationally, and PFOA in drinking water lies in the top 7.0% nationally. Modeled transportation noise is in the top 9.3% nationally, radon registers in the top 13.2% nationally, and disaster risk lies in the top 14.3% nationally.
Set beside the wider area around it, park land runs far lower than the surrounding ZIPs on this measure. For clarity, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. 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. ZIP 40205, 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 0.44 years of 78.6, 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.
