Floodplain exposure
90.3%
in the top 0.7% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
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.

Full methodology ›The read
Letha, Idaho (ZIP 83636) ranks in the bottom 34% nationally (21,193rd) and the bottom 24% of Idaho (205th).
Several readings make the pressure on this area plain: floodplain exposure stands in the top 0.7% nationally, and modeled mammography sits in the bottom 2.2% nationally. Modeled pfas resides in the top 3.7% nationally, and slow internet speeds stands in the top 4.2% nationally. Modeled fine-particle sits in the top 5.6% nationally, and arsenic resides in the top 6.0% nationally. On the encouraging side, housing-cost burden stands at the national minimum, and distance to a Superfund site sits in the top 6.6% nationally. Unemployment resides at the national minimum, shared with about 15% of ZIPs. Modeled loneliness stands in the bottom 7.9% nationally.
Against its neighbors, slow internet speeds runs far higher than the surrounding ZIPs on this measure. For context, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. The closest ZIP that ranks healthier overall is ZIP 83617, 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 1.15 years of 76.7, 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. How distance is measured
