Full methodology ›The read
Crownsville, Maryland (ZIP 21032), by its overall standing, sits in the top 5.3% healthiest ZIPs nationally (1,671st) and the top 15% of Maryland (69th).
The profile opens balanced, with readings on either hand: household income stands in the top 2.4% nationally, modeled mammography lands in the top 1.2% nationally, and modeled transportation is in the bottom 3.2% nationally. Modeled food insecurity resides in the bottom 5.8% nationally, modeled utility shutoff rests in the bottom 6.6% nationally, and poverty lies in the bottom 7.3% nationally. Modeled independent living disability sits in the bottom 4.2% nationally, and housing insecurity settles in the bottom 8.1% nationally. Modeled cognitive disability registers in the bottom 5.9% nationally. By contrast, modeled pfas stands in the top 8.8% nationally.
Held up against its neighbors, park land runs far higher than the surrounding ZIPs on this measure. Defined in plain terms, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. The nearest ZIP ranking healthier overall is ZIP 21012, just across the boundary. Looking wider, the ZIP also sits on the healthier half of the national range on at least seven of the ten good-life measures tracked here, from quiet and green space to nearby care, a combination reached by about one in twenty-five US ZIP codes.

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 0.95 years of 81.0, 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
