The share of households spending 30% or more of their income on housing.
Full methodology ›Child-care access

Higher is healthier
ST91stUS87thDefinition & 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 ›Radon
2.4 pCi/L
in the top 23% nationally
Lower is healthier
ST91stUS77thDefinition & 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 ›The read
Working only from the data in hand, Junction City, Kentucky (ZIP 40440) lands in the bottom 16% nationally (26,858th) and the top 33% of Kentucky (248th), based on limited data; treat as directional.
What little the measures show is worth setting out plainly: distance to a Superfund site resides in the top 9.7% nationally, and modeled disaster risk lands in the bottom 10.6% nationally. Childcare registers in the top 13.4% nationally, and modeled industrial-pollution burden sits in the bottom 17% nationally. On the other hand, poverty rests in the top 6.9% nationally, modeled transportation noise is in the top 8.3% nationally, and housing-cost burden stands in the top 10.1% nationally. Modeled mammography settles in the bottom 11.3% nationally, households without a vehicle lies in the top 12.9% nationally, and modeled loud transportation noise resides in the top 13.2% nationally.
To translate a couple of terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Overall, the nearest healthier neighbor is ZIP 40422, 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.

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 3.09 years of 74.7, 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.
