Lithium in drinking water
9.6 µg/L
in the bottom 4.0% nationally
Lower is healthier
ST8thUS4thDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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 ›Subsidized affordable housing
378 units
in the top 6.3% nationally
Higher is healthier
ST94thUS94thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Arsenic in groundwater
16.9%
in the top 8.4% nationally
Lower is healthier
ST68thUS92ndDefinition & 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 ›Outer-floodplain exposure
2.1%
in the top 14.6% nationally
Lower is healthier
ST92ndUS85thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Natural-disaster risk
in the top 15% nationally
Lower is healthier
ST95thUS85thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›The read
Franklin, Indiana (ZIP 46131), by its composite score, sits in the top 45% healthiest ZIPs nationally (14,408th) and the top 27% of Indiana (206th).
Where the data is kindest to this area, a few readings lead the way: lithium in drinking water sits in the bottom 4.0% nationally. Distance to an emergency room lies at the national minimum, shared with about 11% of ZIPs. Subsidized affordable housing rests in the top 6.3% nationally. Distance to a community health center resides at the national minimum, shared with about 23% of ZIPs. Distance to a nursing home is at the national minimum, shared with about 27% of ZIPs. Physicians lands in the top 14.9% nationally. On the other hand, modeled arsenic stands in the top 8.4% nationally, and expected annual loss registers in the top 12.3% nationally. Outer-floodplain exposure settles in the top 14.6% nationally, and modeled disaster risk sits in the top 15% nationally.
Next to the surrounding area, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. For a healthier comparison close by, see ZIP 46106, 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 0.88 years of 78.0, 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.
