Basalt, Colorado (ZIP 81621), overall, ranks in the top 6.1% healthiest ZIPs nationally (1,935th) and the top 12.6% of Colorado (63rd).
This area's measures are easy to read as a mixed set: park land registers in the top 0.7% nationally, modeled industrial-pollution burden resides in the bottom 1.5% nationally, and modeled obesity settles in the bottom 2.8% nationally. Recreation is in the top 2.1% nationally, modeled air-toxics cancer risk sits in the bottom 2.8% nationally, and physicians lands in the top 3.2% nationally.

Modeled short sleep rests in the bottom 3.8% nationally, and humid heat registers in the bottom 4.8% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. ZIP 81645, just across the boundary, comes out healthier overall.

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

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.
