Full methodology ›The read
On the composite measure, Bonanza, Colorado (ZIP 81155) stands in the bottom 49% nationally (16,355th) and the bottom 27% of Colorado (367th), based on limited data; treat as directional.
A number of readings press hard on the profile and set its tone: walkability lands in the bottom 1.9% nationally, and distance to an emergency room settles in the top 3.2% nationally. Modeled energy burden rests in the top 4.6% nationally, and mammography lands in the bottom 8.3% nationally. On the brighter side, modeled humid heat settles in the bottom 1.7% nationally, park land rests in the top 2.0% nationally, and modeled air-toxics cancer risk lands in the bottom 2.8% nationally. Distance to a hazardous-chemical facility settles in the top 3.7% nationally. Households without a vehicle rests at the national minimum, shared with about 16% of ZIPs. Poverty lands in the bottom 8.5% nationally.
Set beside the wider area around it, park land runs far higher than the surrounding ZIPs on this measure. For clarity, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. ZIP 81149, 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 3.24 years of 87.5, 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.
