Natural-disaster risk

ST95thUS96thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.

Lower is healthier
ST83rdUS96thDefinition & source ›
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.

ST66thUS95thDefinition & 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.

The share of residents served by public water systems where PFAS — man-made “forever chemicals” that build up in the body and environment instead of breaking down — were 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.

The read
ZIP 70056, one of several in Gretna, Louisiana, on the composite measure, lands in the bottom 29% nationally (22,831st) and the top 24% of Louisiana (124th).
The readings split fairly evenly between strengths and concerns: walkability settles in the top 6.4% nationally. Working the other way, modeled disaster risk stands in the top 3.6% nationally, outer-floodplain exposure is in the top 4.4% nationally, and floodplain exposure rests in the top 4.6% nationally. Modeled tree cover sits at the national minimum, and PFAS in drinking water registers at the national maximum. Modeled humid heat lands in the top 5.9% nationally, and loneliness resides in the top 6.0% nationally. Modeled short sleep lies in the top 6.7% nationally, and utility shutoff settles in the top 7.2% nationally.
Set against the neighboring ZIPs, outer-floodplain exposure runs far lower than the surrounding ZIPs on this measure. In everyday language, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". A healthier neighbor overall sits at ZIP 70037, 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 0.57 years of 75.7, 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
