In its overall standing, Hamilton, Colorado (ZIP 81638) lands in the bottom 16% nationally (26,847th) and the bottom 1.8% of Colorado (493rd), based on limited data; treat as directional.
Several serious readings shape the profile and deserve first mention: slow internet speeds settles in the top 1.4% nationally, modeled mammography is in the bottom 2.9% nationally, and walkability sits in the bottom 2.1% nationally. Modeled coronary heart disease lands in the top 3.6% nationally, hearing disability lies in the top 4.5% nationally, and stroke stands in the top 5.3% nationally. Poverty rests in the top 5.1% nationally. On the better side, modeled humid heat registers in the bottom 2.7% nationally, and air-toxics cancer risk resides in the bottom 2.8% nationally. Unemployment settles at the national minimum, shared with about 15% of ZIPs.
Against the wider neighborhood, slow internet speeds runs far higher than the surrounding ZIPs on this measure. Put simply, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. On the overall standing, ZIP 80467, just across the boundary, ranks healthier.

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 1.68 years of 82.7, 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.
