What defines this ZIP

Subsidized affordable housing
1,033 units
in the top 1.3% nationally
Higher is healthier
ST96thUS99thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Fine-particle (PM2.5) exceedance
2.2%
in the top 3.8% nationally
Lower is healthier
ST86thUS96thDefinition & 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 ›Dental provider access
0.94 per 1,000 residents
in the top 7.9% nationally
Higher is healthier
ST89thUS92ndDefinition & source ›
The number of dental offices 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 ›Humid extreme heat
11.9 days/year
in the bottom 8.8% nationally
Lower is healthier
ST58thUS9thDefinition & 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 ›Distance to a Superfund site
1.5 mi
in the bottom 8.9% nationally
Higher is healthier
ST18thUS9thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›PFOS in drinking water
89.2%
in the top 9.3% nationally
Lower is healthier
ST92ndUS91stDefinition & source ›
The share of residents served by public water systems where PFOS, one of the most common “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 ›Energy-cost burden
1.6%
in the bottom 6.5% nationally
Lower is healthier
ST29thUS6thDefinition & 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
0.52%
in the bottom 9.8% nationally
Lower is healthier
ST13thUS10thDefinition & 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 ›Short sleep
30%
in the bottom 9.7% nationally
Lower is healthier
ST30thUS10thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Mammography
80.1%
in the top 10.6% nationally
Higher is healthier
ST99thUS89thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›The read
On the composite measure, ZIP 99223, one of several in Spokane, Washington stands in the top 14.1% healthiest ZIPs nationally (4,511th) and the top 18% of Washington (107th).
A profile of give and take, with clear readings each way: subsidized affordable housing resides in the top 1.3% nationally, and dental providers stands in the top 7.9% nationally. Modeled humid heat sits in the bottom 8.8% nationally, and energy burden resides in the bottom 6.5% nationally. Floodplain exposure stands in the bottom 9.8% nationally, modeled short sleep sits in the bottom 9.7% nationally, and fatal road crashes resides in the bottom 10.8% nationally. On the other side, modeled fine-particle stands in the top 3.8% nationally, distance to a Superfund site sits in the bottom 8.9% nationally, and PFOS in drinking water resides in the top 9.3% nationally.
Set beside the wider area around it, park land runs far lower than the surrounding ZIPs on this measure. For clarity, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. ZIP 99036, just across the boundary, ranks better overall among the ZIPs nearby.

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 0.55 years of 80.8, 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
