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.

Full methodology ›The read
From the measures that could be gathered, Henderson, Kentucky (ZIP 42420) lands in the bottom 8.1% nationally (29,490th) and the top 50% of Kentucky (368th), based on limited data; treat as directional.
So far as the data reaches, a few readings can be drawn: subsidized affordable housing rests in the top 4.5% nationally. Distance to an emergency room resides at the national minimum, shared with about 11% of ZIPs. Distance to a community health center is at the national minimum, shared with about 23% of ZIPs. By contrast, modeled industrial-pollution burden lands in the top 0.09% nationally, expected annual loss stands in the top 4.7% nationally, and short sleep registers in the top 6.3% nationally. Modeled disaster risk settles in the top 7.3% nationally, distance to a Superfund site sits in the bottom 8.7% nationally, and floodplain exposure lies in the top 10.3% nationally. Modeled loud transportation noise rests in the top 10.4% nationally.
Beside the areas that surround it, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Among nearby ZIPs, the nearest healthier one overall is ZIP 42301, 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 0.43 years of 75.2, 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.
