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.
Distance to a Superfund site
In this ZIP
at the national minimum
Higher is healthier
ST1stUS1stDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Outpatient-care access
0.81 per 1,000 residents
in the top 3.0% nationally
Higher is healthier
ST97thUS97thDefinition & source ›
The number of outpatient clinics 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 ›Tooth loss
27%
in the top 5.2% nationally
Lower is healthier
ST67thUS95thDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›PFOA in drinking water
96.9%
in the top 5.5% nationally
Lower is healthier
ST94thUS95thDefinition & 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 ›Homeownership rate
98%
in the top 5.8% nationally
Higher is healthier
ST91stUS94thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›Short sleep
42.7%
in the top 7.2% nationally
Lower is healthier
ST68thUS93rdDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Park land
14.9%
in the top 8.9% nationally
Higher is healthier
ST95thUS91stDefinition & source ›
The share of this ZIP’s land area that is public parkland.
Full methodology ›Poverty rate
3.8%
in the bottom 13.0% nationally
Lower is healthier
ST8thUS13thDefinition & source ›
The share of residents whose income is below the federal poverty line, from the Census Bureau’s American Community Survey.
Full methodology ›Recreation access
0.81 per 1,000 residents
in the top 13.5% nationally
Higher is healthier
ST94thUS87thDefinition & 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.
Full methodology ›Fatal road crashes
4.2 per 100,000 residents per year
in the bottom 16% nationally
Lower is healthier
ST7thUS16thDefinition & 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 ›The read
Given the gaps in coverage here, Brooks, Kentucky (ZIP 40109) lands in the bottom 5.3% nationally (30,382nd) and the bottom 42% of Kentucky (431st), based on limited data; treat as directional.
On what has been documented so far, the readings are limited but real: outpatient stands in the top 3.0% nationally, homeownership lands in the top 5.8% nationally, and park land is in the top 8.9% nationally. Modeled tree cover resides in the top 12.2% nationally, and poverty rests in the bottom 13.0% nationally. Working the other way, distance to a Superfund site lies at the national minimum, and modeled tooth loss sits in the top 5.2% nationally. PFOA in drinking water settles in the top 5.5% nationally, and modeled short sleep registers in the top 7.2% nationally. Modeled transportation noise stands in the top 12.6% nationally.
Held up against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The nearest ZIP ranking healthier overall is ZIP 40165, just across the boundary.
What’s driving this score
Nine domains make up the ZipVitals Score — here is how this ZIP does on each, and how much each one counts. Compare it against the US, this state and the Louisville/Jefferson County, KY-IN metro area.

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

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.
