Mammography
65.1%
in the bottom 3.0% nationally
Higher is healthier
ST20thUS3rdDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Arsenic in groundwater
30.8%
in the top 3.0% nationally
Lower is healthier
ST90thUS97thDefinition & 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 ›Elder-services access
0.28 per 1,000 residents
in the top 5.1% nationally
Higher is healthier
ST93rdUS95thDefinition & source ›
The number of services for older adults and people with disabilities 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 ›Fine-particle (PM2.5) exceedance
1.6%
in the top 6.0% nationally
Lower is healthier
ST55thUS94thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Park land
21.6%
in the top 6.4% nationally
Higher is healthier
ST82ndUS94thDefinition & source ›
The share of this ZIP’s land area that is public parkland.
Full methodology ›Crowded housing

in the top 8.0% nationally
Lower is healthier
ST91stUS92ndDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.
Full methodology ›PFAS in drinking water
10.1%
in the bottom 9.2% nationally
Lower is healthier
ST26thUS9thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Fatal road crashes
34.5 per 100,000 residents per year
in the top 9.9% nationally
Lower is healthier
ST84thUS90thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›The read
On balance, and by the composite measure, Melba, Idaho (ZIP 83641) ranks in the bottom 40% nationally (19,154th) and the bottom 31% of Idaho (185th), based on limited data; treat as directional.
Neither strongly one way nor the other, the measures sit mixed: elder services settles in the top 5.1% nationally, and park land lies in the top 6.4% nationally. Modeled pfas resides in the bottom 9.2% nationally. Against that, modeled mammography lands in the bottom 3.0% nationally, arsenic registers in the top 3.0% nationally, and fine-particle sits in the top 6.0% nationally. Crowded housing rests in the top 8.0% nationally. Fiber broadband is at the national minimum, shared with about 19% of ZIPs. Fatal road crashes stands in the top 9.9% nationally, and modeled hearing disability settles in the top 10.1% nationally.
Compared with the ZIPs it borders, park land runs far higher than the surrounding ZIPs on this measure. In plainer terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. For a healthier nearby ZIP overall, look to ZIP 83607, 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 1.09 years of 79.7, 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. How distance is measured
