Arsenic in groundwater
68.8%
in the top 0.2% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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 ›Radon
2.9 pCi/L
in the top 11.6% nationally
Lower is healthier
ST96thUS88thDefinition & 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 ›Energy-cost burden
4.6%
in the top 14.6% nationally
Lower is healthier
ST91stUS85thDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Mammography
71.6%
in the bottom 22% nationally
Higher is healthier
ST8thUS22ndDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Air-toxics cancer risk
20 per million
in the bottom 25% nationally
Lower is healthier
ST1stUS25thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›Distance to a Superfund site
31.1 mi
in the top 27% nationally
Higher is healthier
ST96thUS73rdDefinition & 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 ›The read
By its overall health score, Lynn, Indiana (ZIP 47355) lands in the bottom 35% nationally (20,897th) and the bottom 36% of Indiana (486th).
Neither strongly one way nor the other, the measures sit mixed: floodplain exposure lands in the bottom 10.7% nationally, and modeled disaster risk registers in the bottom 12.0% nationally. Housing-cost burden sits in the bottom 14.9% nationally. Against that, modeled arsenic rests in the top 0.2% nationally, modeled radon is in the top 11.6% nationally, and home broadband subscription stands in the bottom 13.2% nationally. Fatal road crashes settles in the top 13.6% nationally. Distance to a hazardous-chemical facility lies at the national minimum, shared with about 31% of ZIPs. Recreation resides at the national minimum, shared with about 35% of ZIPs. Modeled energy burden lands in the top 14.6% nationally.
To translate a couple of terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Overall, the nearest healthier neighbor is ZIP 47341, 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 1.57 years of 82.1, 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.
