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.
Radon
4.5 pCi/L
in the top 0.8% nationally
Lower is healthier
ST99thUS99thDefinition & 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 ›PFOA in drinking water
96.3%
in the top 5.8% nationally
Lower is healthier
ST94thUS94thDefinition & 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 ›Hearing disability

in the bottom 5.0% nationally
Lower is healthier
ST3rdUS5thDefinition & source ›
The estimated share of adults who are deaf or have serious difficulty hearing.
Full methodology ›Subsidized affordable housing

ST92ndUS93rdDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Distance to a Superfund site

in the bottom 7.6% nationally
Higher is healthier
ST6thUS8thDefinition & 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 ›Child-care access
0.53 per 1,000 residents
in the top 9.3% nationally
Higher is healthier
ST93rdUS91stDefinition & 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 ›Expected annual disaster loss
$0
in the top 9.6% nationally
Lower is healthier
ST98thUS90thDefinition & 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 ›Mobility disability

in the bottom 8.3% nationally
Lower is healthier
ST5thUS8thDefinition & source ›
The estimated share of adults with serious difficulty walking or climbing stairs.
Full methodology ›Independent-living disability

The estimated share of adults who have difficulty doing errands alone, such as visiting a doctor’s office, because of a physical, mental, or emotional condition.
Full methodology ›Dental provider access

in the top 12.3% nationally
Higher is healthier
ST92ndUS88thDefinition & 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 ›The read
Gahanna, Ohio (ZIP 43230), in overall standing, comes out in the top 16% healthiest ZIPs nationally (5,116th) and the top 7.2% of Ohio (84th).
A few readings each way define this mixed profile: modeled hearing disability sits in the bottom 5.0% nationally, subsidized affordable housing stands in the top 7.4% nationally, and childcare resides in the top 9.3% nationally. Modeled mobility disability sits in the bottom 8.3% nationally, modeled independent living disability stands in the bottom 9.2% nationally, and dental providers resides in the top 12.3% nationally. Pulling the other way, modeled radon sits in the top 0.8% nationally, and PFOA in drinking water stands in the top 5.8% nationally. Distance to a Superfund site resides in the bottom 7.6% nationally, and modeled expected annual loss sits in the top 9.6% nationally.
Set within its surrounding area, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. The closest healthier ZIP overall is ZIP 43054, just across the boundary.

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 0.53 years of 80.2, 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. How distance is measured
