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
In overall standing, Perryman, Maryland (ZIP 21130) comes out in the bottom 37% nationally (20,079th) and the bottom 9.9% of Maryland (413th).
The profile opens on the burdens that define it most: housing-cost burden is in the top 0.5% nationally, poverty resides in the top 0.7% nationally, and modeled transportation noise rests in the top 2.0% nationally. Homeownership lies in the bottom 3.1% nationally, household income sits in the bottom 0.3% nationally, and modeled loud transportation noise settles in the top 5.0% nationally. More positively, home broadband subscription registers at the national maximum, and floodplain exposure stands at the national minimum. Lead in tap water lands at the national minimum. Unemployment is at the national minimum, shared with about 15% of ZIPs.
Relative to the ZIPs around it, poverty runs far higher than the surrounding ZIPs on this measure. In plain terms, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". The nearest healthier ZIP overall is ZIP 21001, 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 2.81 years of 79.2, 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.
