This area's measures are easy to read as a mixed set: lithium in drinking water lies in the bottom 1.6% nationally, and modeled transportation noise stands in the bottom 7.8% nationally. Modeled loud transportation noise rests at the national minimum, shared with about 22% of ZIPs. Homeownership registers in the top 13.1% nationally. Crowded housing resides at the national minimum, shared with about 29% of ZIPs. Modeled high cholesterol settles in the bottom 11.0% nationally. Set against that, modeled binge drinking is in the top 1.9% nationally, and PFAS in drinking water sits at the national maximum. Modeled radon lands in the top 12.6% nationally. Distance to a hazardous-chemical facility lies at the national minimum, shared with about 31% of ZIPs.

Defined simply, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. ZIP 52637, just across the boundary, comes out healthier overall.

“Share” is how much of this ZIP’s score the domain accounts for. Percentages are rounded; higher is healthier in every domain. How the score works, and who it compares you with ›

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.74 years of 78.4, 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.
