The number of physicians’ offices located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.

Full methodology ›The read
By the composite measure, ZIP 19806, one of several in Wilmington, Delaware sits in the top 7.5% healthiest ZIPs nationally (2,387th) and the top 14.1% of Delaware (9th).
Where the data leans one way, another reading answers it: physicians resides in the top 1.7% nationally, dental providers lies in the top 1.9% nationally, and transit settles in the top 2.7% nationally. Walkability stands in the top 3.3% nationally, park land is in the top 5.1% nationally, and civic rests in the top 5.1% nationally. Outpatient sits in the top 5.5% nationally. On the other hand, PFOA in drinking water registers at the national maximum, and modeled air-toxics cancer risk lands in the top 2.4% nationally. PFAS in drinking water resides at the national maximum.
Compared with the ZIPs that surround it, walkability runs far higher than the surrounding ZIPs on this measure. In plain language, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 19803, 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 0.75 years of 79.7, 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. How distance is measured
