Full methodology ›The read
Adamstown, Maryland (ZIP 21710) ranks in the top 9.4% healthiest ZIPs nationally (2,996th) and the top 27% of Maryland (124th).
A balanced set of signals defines this area, not any single one: household income lands in the top 2.6% nationally, and modeled transportation settles in the bottom 5.9% nationally. Modeled food insecurity rests in the bottom 7.8% nationally, and cognitive disability lands in the bottom 5.9% nationally. Modeled tooth loss settles in the bottom 4.4% nationally, energy burden rests in the bottom 7.0% nationally, and independent living disability lands in the bottom 6.8% nationally. Poverty settles in the bottom 11.8% nationally, and modeled fair or poor health rests in the bottom 10.3% nationally. By contrast, modeled nitrate lands in the top 4.8% nationally.
Against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. For context, nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Energy burden is the share of household income that goes to home energy bills. The closest ZIP that ranks healthier overall is ZIP 20842, 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 1.37 years of 82.6, 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
