In its overall standing, ZIP 94621, one of several in Oakland, California lands in the bottom 16% nationally (26,897th) and the bottom 12.3% of California (1,509th).
This area's pressures are easy to read across the measures: modeled expected annual loss lands in the top 0.3% nationally, colon screening lies in the bottom 1.8% nationally, and loneliness stands in the top 0.9% nationally. Modeled disaster risk rests in the top 1.4% nationally, outer-floodplain exposure registers in the top 1.8% nationally, and modeled housing insecurity resides in the top 1.8% nationally. Crowded housing settles in the top 1.9% nationally, and housing-cost burden is in the top 1.9% nationally. Modeled loud transportation noise sits in the top 2.2% nationally. On the brighter side, subsidized affordable housing lands in the top 2.0% nationally.
Against the wider neighborhood, expected annual loss runs far higher than the surrounding ZIPs on this measure. Put simply, 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". On the overall standing, ZIP 94501, 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 0.65 years of 74.5, 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
