Radon
3.8 pCi/L
in the top 2.9% nationally
Lower is healthier
ST99thUS97thDefinition & 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 ›Mammography

The estimated share of women aged 50–74 who had a mammogram within the past two years.

Full methodology ›Fatal road crashes

in the top 22% nationally
Lower is healthier
ST92ndUS78thDefinition & 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 ›Fine-particle (PM2.5) exceedance
0.27%
in the top 41% nationally
Lower is healthier
ST1stUS59thDefinition & 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 ›The read
In its overall standing, Candia, New Hampshire (ZIP 03034) lands in the top 17% healthiest ZIPs nationally (5,550th) and the bottom 44% of New Hampshire (137th).
Taken together, the data gives a genuinely mixed reading: modeled mammography is in the top 2.6% nationally, poverty sits in the bottom 5.7% nationally, and household income lands in the top 6.7% nationally. Modeled tooth loss lies in the bottom 3.0% nationally, and tree cover stands in the top 9.3% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Modeled transportation registers in the bottom 12.4% nationally, and fair or poor health resides in the bottom 11.1% nationally. Modeled loneliness settles in the bottom 13.3% nationally. On the other side, modeled radon is in the top 2.9% nationally.
Against the wider neighborhood, park land runs far lower than the surrounding ZIPs on this measure. Put simply, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. On the overall standing, ZIP 03032, just across the boundary, ranks healthier.

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 1.19 years of 79.2, 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
