Full methodology ›The read
ZIP 94538, one of several in Fremont, California, on the composite measure, lands in the top 3.3% healthiest ZIPs nationally (1,053rd) and the top 9.2% of California (157th).
The profile cuts both ways, and the readings bear that out: modeled obesity sits in the bottom 0.5% nationally, household income registers in the top 4.2% nationally, and subsidized affordable housing lands in the top 2.3% nationally. Modeled high blood pressure resides in the bottom 2.3% nationally, modeled coronary heart disease lies in the bottom 2.5% nationally, and dental providers settles in the top 3.8% nationally. Modeled hearing disability stands in the bottom 2.6% nationally. Working the other way, modeled expected annual loss is in the top 0.3% nationally, and disaster risk rests in the top 0.6% nationally. Crowded housing sits in the top 3.5% nationally.
Set against the neighboring ZIPs, expected annual loss runs far higher than the surrounding ZIPs on this measure. In everyday language, 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. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. A healthier neighbor overall sits at ZIP 94536, 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 0.53 years of 81.9, 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
