Several measures weigh most on this area's profile, and they come first: modeled loud transportation noise sits in the top 2.7% nationally, and outer-floodplain exposure is in the top 3.2% nationally. Modeled expected annual loss settles in the top 4.1% nationally, and transportation noise resides in the top 5.9% nationally. Modeled loneliness registers in the top 6.3% nationally, crowded housing rests in the top 6.3% nationally, and housing-cost burden stands in the top 6.4% nationally. Distance to a Superfund site lies in the bottom 7.6% nationally, and modeled colon screening lands in the bottom 9.5% nationally. On the better side, subsidized affordable housing sits in the top 1.0% nationally.
Read against the ZIPs closest to it, subsidized affordable housing runs far higher than the surrounding ZIPs on this measure. To spell things out, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Close by, ZIP 94534, just across the boundary, ranks healthier overall.

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 0.60 years of 77.8, 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
