On the composite measure, Greensboro, Maryland (ZIP 21639) stands in the bottom 26% nationally (23,882nd) and the bottom 5.3% of Maryland (434th).
A profile of give and take, with clear readings each way: elder services sits in the top 6.1% nationally. Modeled loud transportation noise resides at the national minimum, shared with about 22% of ZIPs. Distance to a community health center stands at the national minimum, shared with about 23% of ZIPs. Childcare sits in the top 12.6% nationally, and modeled industrial-pollution burden resides in the bottom 14.0% nationally. On the other side, distance to an emergency room stands in the top 10.0% nationally, modeled short sleep sits in the top 14.0% nationally, and modeled obesity resides in the top 13.0% nationally. Modeled housing insecurity stands in the top 18% nationally, and households without a vehicle sits in the top 18% nationally.
For clarity, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. 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. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. ZIP 19943, just across the boundary, ranks better overall among the ZIPs nearby.

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 1.12 years of 75.6, 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.
