Full methodology ›The read
By its overall health score, Harmans, Maryland (ZIP 21077) lands in the top 13.1% healthiest ZIPs nationally (4,197th) and the top 38% of Maryland (174th).
Neither strongly one way nor the other, the measures sit mixed: modeled mammography resides in the top 0.05% nationally, and poverty lands at the national minimum. Home broadband subscription registers at the national maximum, and lead in tap water sits at the national minimum. Against that, unemployment rests in the top 0.4% nationally, modeled loud transportation noise is in the top 0.5% nationally, and housing-cost burden stands in the top 0.8% nationally. Modeled transportation noise settles in the top 1.5% nationally, modeled air-toxics cancer risk lies in the top 2.1% nationally, and slow internet speeds resides in the top 3.5% nationally.
Weighed against the ZIPs nearby, unemployment runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Overall, the nearest healthier neighbor is ZIP 21076, 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 1.99 years of 81.7, 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
