Subsidized affordable housing
892 units
in the top 1.8% nationally
Higher is healthier
ST94thUS98thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›PFAS in drinking water
80.4%
in the top 1.9% nationally
Lower is healthier
ST95thUS98thDefinition & 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 ›Lead in tap water
11 ppb
in the top 2.2% nationally
Lower is healthier
US98thDefinition & 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 ›Floodplain exposure
0.00%
at the national minimum
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 ›Homeownership rate
32.1%
in the bottom 3.6% nationally
Higher is healthier
ST4thUS4thDefinition & source ›
The share of occupied homes that are owned, rather than rented, by the people living in them.
Full methodology ›Fine-particle (PM2.5) exceedance

Lower is healthier
ST82ndUS96thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Crowded housing

ST95thUS96thDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.

Full methodology ›The read
Airway Heights, Washington (ZIP 99001), by its composite score, sits in the bottom 25% nationally (23,926th) and the bottom 7.3% of Washington (539th).
The measures that matter most for this area lead the way: modeled pfas resides in the top 1.9% nationally, and lead in tap water is in the top 2.2% nationally. Homeownership lands in the bottom 3.6% nationally, and modeled fine-particle stands in the top 4.0% nationally. Crowded housing registers in the top 4.5% nationally, housing-cost burden settles in the top 4.7% nationally, and modeled tree cover sits at the national minimum. Unemployment lies in the top 6.6% nationally. On the better side, subsidized affordable housing rests in the top 1.8% nationally, and floodplain exposure resides at the national minimum.
Next to the surrounding area, park land runs far lower than the surrounding ZIPs on this measure. For anyone unfamiliar, 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard.

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 2.04 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.
