Full methodology ›The read
Oral, South Dakota (ZIP 57766), in overall standing, comes out in the top 40% healthiest ZIPs nationally (12,894th) and the bottom 40% of South Dakota (217th).
A few readings each way define this mixed profile: distance to a hazardous-chemical facility resides in the top 1.3% nationally, homeownership sits at the national maximum, and modeled air-toxics cancer risk stands in the bottom 2.8% nationally. Fiber broadband resides in the top 5.4% nationally. Unemployment sits at the national minimum, shared with about 15% of ZIPs. Households without a vehicle stands at the national minimum, shared with about 16% of ZIPs. Housing-cost burden resides in the bottom 11.7% nationally.

Distance to a community health center resides in the top 3.8% nationally.
Defined simply, for reference, 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. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. The closest healthier ZIP overall is ZIP 57744, about 6.0 miles away.

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 1.85 years of 79.8, 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.
