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.

Full methodology ›The read
Judged by its overall standing, Rosemead, California (ZIP 91770) sits in the top 38% healthiest ZIPs nationally (12,136th) and the bottom 48% of California (889th).
A balanced showing across the data, with a few readings each side: modeled obesity settles in the bottom 1.0% nationally, modeled binge drinking lands in the bottom 1.6% nationally, and lead in tap water rests at the national minimum. On the other hand, modeled colon screening settles in the bottom 1.2% nationally, loneliness lands in the top 0.9% nationally, and air-toxics cancer risk rests in the top 2.1% nationally. Modeled expected annual loss settles in the top 2.2% nationally, and crowded housing lands in the top 2.7% nationally. Modeled loud transportation noise rests in the top 3.5% nationally, and fine-particle settles in the top 4.3% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. A healthier nearby ZIP overall is ZIP 91755, 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 0.52 years of 83.4, 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
