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.
Full methodology ›The read
On the limited readings gathered so far, ZIP 18101, one of several in Allentown, Pennsylvania lands in the bottom 5.1% nationally (30,449th) and the bottom 2.4% of Pennsylvania (1,707th), based on limited data; treat as directional.
On the measures in hand, a few readings come through: walkability settles in the top 0.08% nationally, mental-health providers lands in the top 1.4% nationally, and recreation rests in the top 2.3% nationally. Transit settles in the top 2.6% nationally, outpatient lands in the top 3.2% nationally, and elder services rests in the top 3.3% nationally. Against that, homeownership settles in the bottom 1.3% nationally, and housing-cost burden lands in the top 1.4% nationally. Modeled colon screening rests in the bottom 4.3% nationally, and outer-floodplain exposure settles in the top 3.6% nationally.
Placed beside its immediate neighbors, walkability runs far higher than the surrounding ZIPs on this measure. Put plainly, 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 nearby ZIP overall is ZIP 18103, less than a tenth of a mile away.

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 0.91 years of 76.1, 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.
