Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
PFAS in drinking water
7.1%
in the bottom 3.5% nationally
Lower is healthier
ST8thUS3rdDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Grocery access
0.3 per 1,000 residents
in the top 3.6% nationally
Higher is healthier
ST98thUS96thDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Natural-disaster risk
in the top 4.3% nationally
Lower is healthier
ST84thUS96thDefinition & 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 ›Humid extreme heat
11 days/year
in the bottom 8.0% nationally
Lower is healthier
ST54thUS8thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Energy-cost burden
1.7%
in the bottom 7.7% nationally
Lower is healthier
ST33rdUS8thDefinition & 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 ›PFOA in drinking water
53.8%
in the top 16% nationally
Lower is healthier
ST90thUS84thDefinition & source ›
The share of residents served by public water systems where PFOA, one of the man-made “forever chemicals,” was detected in EPA testing.
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
On balance, and by the composite measure, Amboy, Washington (ZIP 98601) ranks in the top 32% healthiest ZIPs nationally (10,241st) and the top 45% of Washington (262nd).
A number of signals point in a favorable direction for this area: modeled pfas sits in the bottom 3.5% nationally, and grocery rests in the top 3.6% nationally. Modeled humid heat is in the bottom 8.0% nationally, and energy burden stands in the bottom 7.7% nationally. Modeled loud transportation noise settles at the national minimum, shared with about 22% of ZIPs. Modeled short sleep lies in the bottom 11.0% nationally, distance to a hazardous-chemical facility resides in the top 15% nationally, and modeled tooth loss lands in the bottom 13.0% nationally. Working the other way, modeled disaster risk registers in the top 4.3% nationally, and PFOA in drinking water sits in the top 16% nationally.
Compared with the ZIPs it borders, industrial-pollution burden runs far lower than the surrounding ZIPs on this measure. In plainer terms, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. For a healthier nearby ZIP overall, look to ZIP 98629, 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 1.13 years of 79.5, 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.
