Overall, Marbury, Maryland (ZIP 20658) lands in the top 35% healthiest ZIPs nationally (11,266th) and the bottom 28% of Maryland (329th).
The measures that set this area apart are worth putting up front: modeled disaster risk registers in the bottom 9.3% nationally, and expected annual loss rests in the bottom 10.5% nationally. Modeled loud transportation noise stands at the national minimum, shared with about 22% of ZIPs. Transit lies in the top 13.1% nationally, modeled transportation noise lands in the bottom 16% nationally, and modeled mammography sits in the top 14.9% nationally. Set against that, distance to a Superfund site is in the bottom 6.1% nationally, floodplain exposure settles in the top 8.5% nationally, and crowded housing resides in the top 16% nationally. Recreation registers at the national minimum, shared with about 35% of ZIPs.
Set beside the nearby areas, park land runs far lower than the surrounding ZIPs on this measure. A note on the terms: distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. For a healthier nearby comparison, ZIP 20640, just across the boundary, ranks better 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 2.25 years of 78.7, 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.
