Full methodology ›The read
Overall, ZIP 94109, one of several in San Francisco, California places in the top 7.1% healthiest ZIPs nationally (2,266th) and the top 17% of California (290th).
The data opens on a genuinely even set of readings: modeled obesity resides in the bottom 0.4% nationally, and subsidized affordable housing is in the top 0.5% nationally. Walkability lands in the top 0.9% nationally, and modeled energy burden stands in the bottom 0.3% nationally. On the other side, modeled expected annual loss registers in the top 0.02% nationally, disaster risk settles in the top 0.07% nationally, and loud transportation noise sits in the top 0.3% nationally. Modeled transportation noise lies in the top 0.9% nationally, households without a vehicle rests in the top 1.0% nationally, and homeownership resides in the bottom 1.8% nationally.
Beside the areas that surround it, expected annual loss runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, 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. Among nearby ZIPs, the nearest healthier one overall is ZIP 94105, 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 0.44 years of 80.5, 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
