US1stDefinition & source ›
The lead level at the 90th percentile of tap-water samples reported by the public water systems serving this ZIP, in parts per billion — the EPA requires action above 15 ppb.
Measured from EPA records for the public water systems that serve this ZIP. Households on private wells — roughly 30% of the US population — are not covered by this measure, and this figure says nothing about their water.
Full methodology ›Outer-floodplain exposure
7.0%
in the top 5.4% nationally
Lower is healthier
ST87thUS95thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›The read
Judged by its overall standing, ZIP 94541, one of several in Hayward, California sits in the top 25% healthiest ZIPs nationally (7,891st) and the top 41% of California (705th).
A balanced showing across the data, with a few readings each side: walkability is in the top 3.5% nationally, subsidized affordable housing lies in the top 3.8% nationally, and lead in tap water registers at the national minimum. On the other hand, modeled expected annual loss is in the top 0.4% nationally, loud transportation noise lies in the top 1.3% nationally, and disaster risk registers in the top 2.3% nationally. Modeled transportation noise is in the top 2.4% nationally, and crowded housing lies in the top 2.5% nationally. Modeled loneliness registers in the top 3.7% nationally, and outer-floodplain exposure is in the top 5.4% nationally.
Placed beside its immediate neighbors, expected annual loss runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. A healthier nearby ZIP overall is ZIP 94542, 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 0.51 years of 78.6, 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
