By the composite measure, ZIP 94555, one of several in Fremont, California sits in the top 1.1% healthiest ZIPs nationally (326th) and the top 3.1% of California (53rd).
The profile cuts both ways, and the readings bear that out: household income sits in the top 0.7% nationally, park land registers at the national maximum, and modeled obesity lands in the bottom 0.2% nationally. Modeled utility shutoff resides in the bottom 2.0% nationally, hearing disability lies in the bottom 1.8% nationally, and high blood pressure settles in the bottom 2.5% nationally. Modeled cognitive disability stands in the bottom 1.1% nationally, and coronary heart disease is in the bottom 2.3% nationally. Modeled independent living disability rests in the bottom 0.7% nationally. Working the other way, floodplain exposure sits in the top 3.3% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". ZIP 94539, about 3.6 miles away, 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 0.82 years of 82.7, 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
