Radon
3.7 pCi/L
in the top 3.3% nationally
Lower is healthier
ST66thUS97thDefinition & 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 ›Fiber broadband
99.6%
in the top 3.2% nationally
Higher is healthier
ST88thUS97thDefinition & source ›
The share of homes where fiber-optic internet service is available.
Full methodology ›Energy-cost burden
5.4%
in the top 5.6% nationally
Lower is healthier
ST88thUS94thDefinition & 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 ›Transportation noise
0.11%
in the bottom 8.5% nationally
Lower is healthier
ST15thUS8thDefinition & 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 ›Outer-floodplain exposure
2.8%
in the top 11.6% nationally
Lower is healthier
ST94thUS88thDefinition & 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 ›High cholesterol
41.3%
in the top 21% nationally
Lower is healthier
ST98thUS79thDefinition & source ›
The estimated share of adults with high cholesterol, among those who have ever been screened for it.
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 ›High blood pressure
41.8%
in the top 24% nationally
Lower is healthier
ST95thUS76thDefinition & source ›
The estimated share of adults who have been told by a health professional that they have high blood pressure.
Full methodology ›Binge drinking
17.4%
in the top 26% nationally
Lower is healthier
ST4thUS74thDefinition & source ›
The estimated share of adults who report binge drinking — five or more drinks on one occasion for men, four or more for women.
Full methodology ›Distance to a hazardous-chemical facility
4.7 mi

Higher is healthier
ST97thUS71stDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›The read
By the composite measure, New Market, Iowa (ZIP 51646) sits in the bottom 49% nationally (16,505th) and the bottom 26% of Iowa (683rd).
The profile cuts both ways, and the readings bear that out: fiber broadband settles in the top 3.2% nationally, and modeled transportation noise stands in the bottom 8.5% nationally. Modeled loud transportation noise is at the national minimum, shared with about 22% of ZIPs. Housing-cost burden rests in the bottom 12.3% nationally. Crowded housing sits at the national minimum, shared with about 29% of ZIPs. Modeled housing insecurity registers in the bottom 17% nationally. Working the other way, modeled radon lands in the top 3.3% nationally, and energy burden resides in the top 5.6% nationally. Outer-floodplain exposure lies in the top 11.6% nationally. Recreation settles at the national minimum, shared with about 35% of ZIPs.
In plain language, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Energy burden is the share of household income that goes to home energy bills. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. ZIP 50833, 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 1.85 years of 80.7, 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.
