Nitrate in drinking water
13.0%
in the top 2.8% nationally
Lower is healthier
ST99thUS97thDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Walkability
2.1 intersections/sq mi
in the bottom 7.7% nationally
Higher is healthier
ST4thUS8thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Homeownership rate
94.7%
in the top 9.0% nationally
Higher is healthier
ST88thUS91stDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›Child-care access
0.53 per 1,000 residents
in the top 9.5% nationally
Higher is healthier
ST95thUS91stDefinition & 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 ›PFOA in drinking water
82.7%
in the top 11.1% nationally
Lower is healthier
ST90thUS89thDefinition & 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 ›Colon-cancer screening
69.6%
in the top 23% nationally
Higher is healthier
ST91stUS77thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Median household income
$97,681
in the top 21% nationally
Higher is healthier
ST94thUS79thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›The read
With coverage still partial across the sources, Bagdad, Kentucky (ZIP 40003) lands in the top 47% healthiest ZIPs nationally (15,004th) and the top 8.3% of Kentucky (61st), based on limited data; treat as directional.
The partial picture points to a handful of readings, with caveats: homeownership lies in the top 9.0% nationally, and childcare stands in the top 9.5% nationally. Crowded housing rests at the national minimum, shared with about 29% of ZIPs. Set against that, modeled nitrate registers in the top 2.8% nationally, and walkability resides in the bottom 7.7% nationally. Fiber broadband settles at the national minimum, shared with about 19% of ZIPs. PFOA in drinking water is in the top 11.1% nationally, and modeled pfas sits in the top 16% nationally. Recreation lands at the national minimum, shared with about 35% of ZIPs. Modeled short sleep lies in the top 17% nationally.
Defined simply, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. ZIP 40067, about 8.6 miles away, comes out healthier overall.
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

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 1.10 years of 75.9, 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.
