Obesity

The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.

ST89thUS98thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.
Full methodology ›Lithium in drinking water

Lower is healthier
ST3rdUS2ndDefinition & source ›
The average detected level of lithium — a natural trace metal with no federal drinking-water limit yet — across the public water systems serving this ZIP, in micrograms per liter.
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 ›Loud transportation noise
3.5%
in the top 2.9% nationally
Lower is healthier
ST81stUS97thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.

Lower is healthier
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 ›Utility shut-off threat

The estimated share of adults whose household was threatened with a utility shut-off in the past 12 months.

The share of this ZIP’s land area that is public parkland.
Full methodology ›Mental-health provider access

Higher is healthier
ST94thUS95thDefinition & source ›
The number of mental-health clinics located inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.
Full methodology ›Natural-disaster risk

ST79thUS95thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.

Full methodology ›The read
In its overall standing, Claremont, California (ZIP 91711) lands in the top 6.1% healthiest ZIPs nationally (1,943rd) and the top 15% of California (260th).
Taken together, the data gives a genuinely mixed reading: modeled obesity rests in the bottom 1.3% nationally, lithium in drinking water registers in the bottom 2.4% nationally, and floodplain exposure resides at the national minimum. Modeled utility shutoff settles in the bottom 4.4% nationally, park land is in the top 4.9% nationally, and mental-health providers sits in the top 4.9% nationally. On the other side, modeled expected annual loss lands in the top 1.7% nationally, and loud transportation noise lies in the top 2.9% nationally. Modeled disaster risk stands in the top 5.0% nationally, and loneliness rests in the top 5.1% nationally.
Against the wider neighborhood, expected annual loss runs far higher than the surrounding ZIPs on this measure. Put simply, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. On the overall standing, ZIP 91765, about 4.6 miles away, ranks healthier.

Findings that name this ZIP
2 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.
Heavy environment, light chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 9.7 (bottom 10%); chronic-disease standing 96.1 (top 10%) — 86 points apart, heavier on the environment than it is on chronic illness.

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 0.71 years of 81.4, 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
