A number of readings press hard on the profile and set its tone: modeled fine-particle sits in the top 1.2% nationally, and walkability resides in the bottom 2.4% nationally. Modeled disaster risk stands in the top 4.0% nationally, and hearing disability sits in the top 5.6% nationally. Slow internet speeds resides in the top 7.7% nationally. Fiber broadband stands at the national minimum, shared with about 19% of ZIPs. On the brighter side, modeled air-toxics cancer risk sits in the bottom 5.6% nationally, modeled humid heat resides in the bottom 9.4% nationally, and distance to a hazardous-chemical facility stands in the top 9.5% nationally. Floodplain exposure sits in the bottom 9.7% nationally.

For context, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. The closest ZIP that ranks healthier overall is ZIP 59827, just across the boundary.

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 2.43 years of 78.7, and it’s very unlikely to be off by more than twice that.

More ZIPs to explore ▾

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.
