What defines this ZIP

Arsenic in groundwater
37.7%
in the top 1.9% nationally
Lower is healthier
ST93rdUS98thDefinition & 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 ›Industrial-pollution burden
in the top 3.7% nationally
Lower is healthier
ST90thUS96thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Recreation access
0.88 per 1,000 residents
in the top 11.5% nationally
Higher is healthier
ST95thUS89thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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 ›Transportation noise
0.41%
in the bottom 13.9% nationally
Lower is healthier
ST6thUS14thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Loneliness

Lower is healthier
ST6thUS19thDefinition & source ›
The estimated share of adults who report feeling lonely.
Full methodology ›Air-toxics cancer risk

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 ›The read
By the composite measure, Colfax, Indiana (ZIP 46035) sits in the top 42% healthiest ZIPs nationally (13,526th) and the top 23% of Indiana (177th).
The readings split fairly evenly between strengths and concerns: recreation sits in the top 11.5% nationally, floodplain exposure registers in the bottom 13.7% nationally, and modeled transportation noise lands in the bottom 13.9% nationally. Outer-floodplain exposure resides at the national minimum, shared with about 36% of ZIPs. Modeled disaster risk lies in the bottom 18% nationally, and loneliness settles in the bottom 19% nationally. Working the other way, modeled arsenic stands in the top 1.9% nationally, and industrial-pollution burden is in the top 3.7% nationally. Physicians rests at the national minimum, shared with about 38% of ZIPs. Modeled radon sits in the top 19% nationally.
Compared with the ZIPs that surround it, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. In plain language, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. ZIP 46071, just across the boundary, ranks healthier overall.

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 1.07 years of 80.4, 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.
