Full methodology ›The read
By the composite health measure, Big Pool, Maryland (ZIP 21711) ranks in the top 29% healthiest ZIPs nationally (9,346th) and the bottom 35% of Maryland (299th).
The picture here is genuinely mixed, with readings on both sides: homeownership stands at the national maximum. Households without a vehicle lies at the national minimum, shared with about 16% of ZIPs. Home broadband subscription lands in the top 8.2% nationally, modeled tree cover sits in the top 8.8% nationally, and modeled transportation is in the bottom 13.7% nationally. Modeled expected annual loss settles in the bottom 15% nationally, park land resides in the top 17% nationally, and modeled food insecurity registers in the bottom 17% nationally. On the other side, modeled radon rests in the top 9.6% nationally, and distance to a nursing home stands in the top 16% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Close by, ZIP 21782, about 9.2 miles away, 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 1.01 years of 77.8, 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.
