ZIP 94509, one of several in Antioch, California ranks in the bottom 45% nationally (17,613th) and the bottom 34% of California (1,136th).
Several readings make the pressure on this area plain: modeled expected annual loss lies in the top 4.3% nationally, and housing-cost burden is in the top 5.8% nationally. Modeled loud transportation noise registers in the top 6.1% nationally, and loneliness lies in the top 6.5% nationally. Crowded housing is in the top 7.4% nationally, modeled housing insecurity registers in the top 9.4% nationally, and modeled tree cover lies in the bottom 10.4% nationally. On the encouraging side, subsidized affordable housing is in the top 1.1% nationally, transit registers in the top 10.7% nationally, and park land lies in the top 10.8% nationally.
Against its neighbors, subsidized affordable housing runs far higher than the surrounding ZIPs on this measure. For context, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. 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 ZIP that ranks healthier overall is ZIP 94531, 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 0.47 years of 76.8, 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
