ZIP 94544, one of several in Hayward, California, in overall standing, comes out in the top 25% healthiest ZIPs nationally (8,087th) and the top 42% of California (718th).
A balanced showing across the data, with a few readings each side: subsidized affordable housing lies in the top 3.6% nationally, and modeled obesity registers in the bottom 6.7% nationally. On the other hand, modeled expected annual loss is in the top 0.4% nationally, modeled disaster risk lies in the top 1.2% nationally, and crowded housing registers in the top 2.0% nationally. Modeled loud transportation noise is in the top 2.5% nationally, and loneliness lies in the top 2.6% nationally. Modeled transportation noise registers in the top 2.9% nationally, and outer-floodplain exposure is in the top 3.7% nationally. Modeled colon screening lies in the bottom 5.0% nationally.
Set within its surrounding area, expected annual loss runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. The closest healthier ZIP overall is ZIP 94541, 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 0.52 years of 80.0, 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
