In its overall standing, ZIP 94552, one of several in Castro Valley, California lands in the top 1.6% healthiest ZIPs nationally (499th) and the top 4.7% of California (80th).
Reading the numbers as a whole, the picture lands somewhere in between: household income stands in the top 0.8% nationally, modeled obesity rests in the bottom 0.9% nationally, and modeled utility shutoff registers in the bottom 2.8% nationally. Modeled cognitive disability resides in the bottom 3.6% nationally, humid heat settles in the bottom 6.2% nationally, and energy burden is in the bottom 2.9% nationally. Home broadband subscription sits in the top 6.3% nationally, and modeled tooth loss lands in the bottom 2.4% nationally. On the other side, modeled disaster risk lies in the top 3.6% nationally, and expected annual loss stands in the top 6.3% nationally.
Against the wider neighborhood, expected annual loss runs far lower than the surrounding ZIPs on this measure. Put simply, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. On the overall standing, ZIP 94556, just across the boundary, ranks healthier.

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 0.92 years of 82.8, 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. How distance is measured
