Median household income

Higher is healthier
ST97thUS98thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›PFAS in drinking water
85.4%
in the top 1.0% nationally
Lower is healthier
ST97thUS99thDefinition & 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 ›Humid extreme heat
3.1 days/year
in the bottom 1.9% nationally
Lower is healthier
ST8thUS2ndDefinition & 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
1.1%
in the bottom 1.3% nationally
Lower is healthier
ST8thUS1stDefinition & 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 ›Lead in tap water
6.2 ppb
in the top 7.4% nationally
Lower is healthier
US93rdDefinition & source ›
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.
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 ›Coronary heart disease

The estimated share of adults who have been told by a health professional that they have coronary heart disease or angina.

Full methodology ›The read
ZIP 98296, one of several in Snohomish, Washington, overall, ranks in the top 9.9% healthiest ZIPs nationally (3,144th) and the top 11.8% of Washington (68th).
This area's measures are easy to read as a mixed set: household income lands in the top 1.9% nationally, modeled humid heat lies in the bottom 1.9% nationally, and modeled energy burden stands in the bottom 1.3% nationally. Modeled coronary heart disease rests in the bottom 5.7% nationally, independent living disability registers in the bottom 4.2% nationally, and mobility disability resides in the bottom 5.9% nationally. Modeled fair or poor health settles in the bottom 5.4% nationally. Set against that, modeled pfas is in the top 1.0% nationally, and lead in tap water sits in the top 7.4% nationally. Modeled air-toxics cancer risk lands in the top 8.1% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, 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. Lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. ZIP 98012, just across the boundary, comes out healthier overall.

Findings that name this ZIP
3 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.
Below what income predicts
The ZIP codes that outlive their incomes
Estimated life expectancy is 80.4 ± 1.6 years. A median household income of $177,583 predicts 82.3 years — 2.0 years below.

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 0.84 years of 80.3, 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.
