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 ›The read
By the composite measure, Alpine, California (ZIP 91901) sits in the top 21% healthiest ZIPs nationally (6,700th) and the top 37% of California (634th).
The profile cuts both ways, and the readings bear that out: park land lies in the top 3.1% nationally, modeled obesity settles in the bottom 9.6% nationally, and floodplain exposure stands in the bottom 8.1% nationally. Distance to a community health center is at the national minimum, shared with about 23% of ZIPs. Home broadband subscription rests in the top 12.9% nationally, and household income sits in the top 11.7% nationally. Transit registers in the top 14.4% nationally, and modeled radon lands in the bottom 16% nationally. Working the other way, modeled disaster risk resides in the top 0.2% nationally, and housing-cost burden lies in the top 8.2% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". ZIP 91916, 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 1.27 years of 82.6, 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.
