Obesity
21%
in the bottom 1.4% nationally
Lower is healthier
ST9thUS1stDefinition & source ›
The estimated share of adults with obesity, defined as a body-mass index of 30 or higher.
Full methodology ›Loud transportation noise
6.4%
in the top 0.8% nationally
Lower is healthier
ST96thUS99thDefinition & 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.
Full methodology ›Median household income
$158,304
in the top 3.1% nationally
Higher is healthier
ST89thUS97thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Lithium in drinking water
9.2 µg/L
in the bottom 1.8% nationally
Lower is healthier
ST1stUS2ndDefinition & 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 ›Energy-cost burden
0.86%
in the bottom 0.6% nationally
Lower is healthier
ST2ndUS1stDefinition & source ›
The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›Floodplain exposure
56.8%
in the top 3.0% nationally
Lower is healthier
ST97thUS97thDefinition & 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 ›High blood pressure
24.8%
in the bottom 2.7% nationally
Lower is healthier
ST6thUS3rdDefinition & source ›
The estimated share of adults who have been told by a health professional that they have high blood pressure.

Lower is healthier
ST89thUS96thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.

Full methodology ›The read
ZIP 94089, one of several in Sunnyvale, California, in overall standing, comes out in the top 4.6% healthiest ZIPs nationally (1,458th) and the top 12.0% of California (205th).
A few readings each way define this mixed profile: modeled obesity lands in the bottom 1.4% nationally, household income rests in the top 3.1% nationally, and lithium in drinking water settles in the bottom 1.8% nationally. Modeled energy burden lands in the bottom 0.6% nationally, high blood pressure rests in the bottom 2.7% nationally, and coronary heart disease settles in the bottom 3.0% nationally. Modeled hearing disability lands in the bottom 3.2% nationally. Pulling the other way, modeled loud transportation noise rests in the top 0.8% nationally, and floodplain exposure settles in the top 3.0% nationally. Modeled transportation noise lands in the top 4.0% nationally.
Set within its surrounding area, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, lithium in drinking water is a natural metal that dissolves into some groundwater and has no federal drinking-water limit yet. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Energy burden is the share of household income that goes to home energy bills. The closest healthier ZIP overall is ZIP 94043, 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 0.98 years of 82.2, 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
