Full methodology ›The read
On the composite measure, Rock Springs, Wyoming (ZIP 82901) stands in the bottom 48% nationally (16,597th) and the bottom 39% of Wyoming (95th), based on limited data; treat as directional.
A number of readings press hard on the profile and set its tone: distance to an emergency room lands in the top 1.2% nationally, and modeled mammography settles in the bottom 3.5% nationally. Modeled colon screening rests in the bottom 4.4% nationally, and disaster risk lands in the top 10.5% nationally. On the brighter side, modeled humid heat settles in the bottom 1.6% nationally, distance to a Superfund site rests in the top 3.2% nationally, and modeled air-toxics cancer risk lands in the bottom 8.0% nationally. Modeled high cholesterol settles in the bottom 5.7% nationally. Modeled extreme heat rests at the national minimum, shared with about 19% of ZIPs. Distance to a community health center lands at the national minimum, shared with about 23% of ZIPs.
For clarity, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. ZIP 82935, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.80 years of 78.9, 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.
