ST1stUS1stDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
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 ›Lead in tap water

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 ›The read
Judged by its overall standing, ZIP 91103, one of several in Pasadena, California sits in the top 40% healthiest ZIPs nationally (12,953rd) and the bottom 46% of California (920th).
A balanced showing across the data, with a few readings each side: subsidized affordable housing lies in the top 3.2% nationally, floodplain exposure registers at the national minimum, and lead in tap water is at the national minimum. Walkability lies in the top 7.1% nationally. On the other hand, modeled expected annual loss registers in the top 1.6% nationally, and colon screening is in the bottom 4.0% nationally. Modeled loneliness lies in the top 3.0% nationally, and housing-cost burden registers in the top 4.9% nationally. Crowded housing is in the top 5.1% nationally, and distance to a Superfund site lies in the bottom 6.0% 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. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. A healthier nearby ZIP overall is ZIP 91001, 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 0.99 years of 79.9, 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
