The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.

Overall, St. Marys, Kansas (ZIP 66536) places in the bottom 49% nationally (16,356th) and the top 47% of Kansas (319th).
The measures fall on both sides for this area, fairly evenly: distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. Distance to a Superfund site stands in the top 16% nationally. Pulling the other way, outer-floodplain exposure registers in the top 6.5% nationally, modeled loud transportation noise settles in the top 8.1% nationally, and distance to a community health center sits in the top 9.1% nationally. Crowded housing lies in the top 10.6% nationally, modeled transportation noise rests in the top 12.3% nationally, and floodplain exposure resides in the top 12.7% nationally. Modeled extreme heat is in the top 12.8% nationally. Distance to a hazardous-chemical facility lands at the national minimum, shared with about 31% of ZIPs.
Beside the areas that surround it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Among nearby ZIPs, the nearest healthier one overall is ZIP 66407, 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 1.04 years of 80.7, 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.
