Overall, Dagsboro, Delaware (ZIP 19939) places in the top 29% healthiest ZIPs nationally (9,345th) and the top 44% of Delaware (28th).
The data opens on a genuinely even set of readings: modeled loneliness stands in the bottom 9.0% nationally, and mammography registers in the top 6.4% nationally. Modeled colon screening settles in the top 7.0% nationally, and homeownership sits in the top 13.5% nationally. Modeled short sleep lies in the bottom 14.0% nationally, and binge drinking rests in the bottom 13.0% nationally. On the other side, modeled high cholesterol resides in the top 0.5% nationally, modeled nitrate is in the top 4.7% nationally, and distance to a Superfund site lands in the bottom 5.3% nationally. Floodplain exposure stands in the top 10.7% nationally.
Beside the areas that surround it, park land runs far lower than the surrounding ZIPs on this measure. For readers new to these terms, 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 Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Among nearby ZIPs, the nearest healthier one overall is ZIP 19930, 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 0.80 years of 78.8, 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.
