Expected annual disaster loss

ST97thUS96thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.

ST92ndUS91stDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Full methodology ›The read
With only part of the picture in hand, ZIP 40229, one of several in Louisville, Kentucky lands in the bottom 27% nationally (23,359th) and the top 22% of Kentucky (161st), based on limited data; treat as directional.
Where the data does reach, it says a few things here: park land settles in the top 15% nationally, and subsidized affordable housing stands in the top 19% nationally. Set against that, modeled expected annual loss is in the top 4.3% nationally, PFOA in drinking water rests in the top 9.1% nationally, and modeled disaster risk sits in the top 9.9% nationally. Modeled loud transportation noise registers in the top 10.4% nationally, and distance to a Superfund site lands in the bottom 12.1% nationally. Crowded housing resides in the top 14.7% nationally, and modeled industrial-pollution burden lies in the top 15% nationally. Modeled transportation noise settles in the top 19% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. ZIP 40047, 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 0.81 years of 76.9, 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.
