Full methodology ›The read
In overall standing, Agar, South Dakota (ZIP 57520) comes out in the top 23% healthiest ZIPs nationally (7,470th) and the top 23% of South Dakota (81st), based on limited data; treat as directional.
The profile opens balanced, with readings on either hand: distance to a Superfund site sits in the top 2.1% nationally, modeled short sleep settles in the bottom 2.2% nationally, and fiber broadband registers in the top 6.4% nationally. Modeled air-toxics cancer risk stands in the bottom 7.1% nationally. Unemployment lands at the national minimum, shared with about 15% of ZIPs. Modeled colon screening is in the top 4.8% nationally. By contrast, walkability resides in the bottom 2.0% nationally, and home broadband subscription rests in the bottom 3.1% nationally. Modeled radon lies in the top 5.8% nationally, and slow internet speeds sits in the top 6.4% nationally.
In plain terms, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. The nearest healthier ZIP overall is ZIP 57501, just across the boundary.

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 0.78 years of 79.4, 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.
