Judged by its overall standing, Dunlap, California (ZIP 93621) sits in the top 46% healthiest ZIPs nationally (14,720th) and the bottom 42% of California (997th).
A balanced showing across the data, with a few readings each side: park land lies in the top 2.3% nationally, homeownership registers at the national maximum, and household income is in the top 5.6% nationally. Modeled colon screening lies in the top 4.6% nationally. Unemployment registers at the national minimum, shared with about 15% of ZIPs. On the other hand, modeled fine-particle is in the top 0.7% nationally, and distance to an emergency room lies in the top 3.2% nationally. Modeled air-toxics cancer risk registers in the top 4.5% nationally, and distance to a nursing home is in the top 4.6% nationally. Walkability lies in the bottom 6.2% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure.

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 1.92 years of 72.6, 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.
