By the composite measure, Hill City, South Dakota (ZIP 57745) sits in the top 14.1% healthiest ZIPs nationally (4,498th) and the top 4.5% of South Dakota (16th).
Where the data leans one way, another reading answers it: park land sits in the top 0.3% nationally, elder services registers in the top 2.5% nationally, and modeled humid heat lands in the bottom 3.5% nationally. Modeled tree cover resides in the top 3.8% nationally, and air-toxics cancer risk lies in the bottom 5.6% nationally. Unemployment settles at the national minimum, shared with about 15% of ZIPs. Modeled cognitive disability stands in the bottom 7.3% nationally, and short sleep is in the bottom 10.1% nationally. On the other hand, walkability rests in the bottom 5.8% nationally, and distance to a community health center sits in the top 10.8% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, 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. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. ZIP 57702, just across the boundary, ranks 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

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 3.51 years of 85.0, 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.
