A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›The read
By the composite health measure, Brandywine, Maryland (ZIP 20613) ranks in the top 14.6% healthiest ZIPs nationally (4,663rd) and the top 41% of Maryland (187th).
The picture here is genuinely mixed, with readings on both sides: household income lands in the top 3.8% nationally, and modeled hearing disability sits in the bottom 3.2% nationally. Modeled mammography is in the top 6.1% nationally, and homeownership settles in the top 10.1% nationally. Modeled binge drinking resides in the bottom 9.9% nationally. Distance to a community health center registers at the national minimum, shared with about 23% of ZIPs. On the other side, distance to a Superfund site rests at the national minimum, modeled short sleep stands in the top 5.1% nationally, and fatal road crashes lies in the top 7.5% nationally. Modeled obesity lands in the top 10.5% nationally.
To spell things out, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. Close by, ZIP 20607, just across the boundary, 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 0.76 years of 78.5, 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.
