Full methodology ›The read
White Hall, Maryland (ZIP 21161) ranks in the top 13.7% healthiest ZIPs nationally (4,390th) and the top 40% of Maryland (182nd).
A balanced set of signals defines this area, not any single one: modeled transportation sits in the bottom 7.6% nationally, and food insecurity resides in the bottom 9.8% nationally. Modeled cognitive disability stands in the bottom 9.5% nationally, and utility shutoff sits in the bottom 12.2% nationally. Modeled independent living disability resides in the bottom 9.2% nationally, colon screening stands in the top 9.5% nationally, and tooth loss sits in the bottom 8.7% nationally. Modeled mammography resides in the top 10.6% nationally. By contrast, modeled nitrate stands in the top 1.3% nationally, and distance to a community health center sits in the top 10.9% nationally.
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. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. The closest ZIP that ranks healthier overall is ZIP 21084, 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 0.64 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.
