What defines this ZIP
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.
Walkability
190 intersections/sq mi
in the top 3.0% nationally
Higher is healthier
ST97thUS97thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
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 ›Fine-particle (PM2.5) exceedance
2.2%
in the top 3.8% nationally
Lower is healthier
ST87thUS96thDefinition & 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 ›PFOS in drinking water
99.4%
in the top 4.3% nationally
Lower is healthier
ST98thUS96thDefinition & 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 ›Fatal road crashes
1.9 per 100,000 residents per year
in the bottom 6.5% nationally
Lower is healthier
ST12thUS6thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Short sleep
29.3%
in the bottom 6.8% nationally
Lower is healthier
ST23rdUS7thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Tooth loss
5.4%
in the bottom 3.0% nationally
Lower is healthier
ST8thUS3rdDefinition & source ›
The estimated share of adults aged 65 and older who have lost all of their natural teeth.
Full methodology ›Dental provider access
0.9 per 1,000 residents
in the top 8.5% nationally
Higher is healthier
ST88thUS92ndDefinition & 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 ›Colon-cancer screening
73.5%
in the top 6.0% nationally
Higher is healthier
ST94thUS94thDefinition & source ›
The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.
Full methodology ›Humid extreme heat
12.3 days/year
in the bottom 9.2% nationally
Lower is healthier
ST60thUS9thDefinition & 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 ›The read
Overall, ZIP 99203, one of several in Spokane, Washington lands in the top 10.2% healthiest ZIPs nationally (3,244th) and the top 12.3% of Washington (71st).
The measures that set this area apart are worth putting up front: walkability settles in the top 3.0% nationally, and floodplain exposure resides at the national minimum. Fatal road crashes registers in the bottom 6.5% nationally, and modeled short sleep rests in the bottom 6.8% nationally. Modeled tooth loss stands in the bottom 3.0% nationally, dental providers lies in the top 8.5% nationally, and modeled colon screening lands in the top 6.0% nationally. Modeled humid heat sits in the bottom 9.2% nationally. Set against that, modeled fine-particle is in the top 3.8% nationally, and PFOS in drinking water settles in the top 4.3% nationally.
Set beside the nearby areas, walkability runs far higher than the surrounding ZIPs on this measure. A note on the terms: fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. 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. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". For a healthier nearby comparison, ZIP 99019, about 11 miles away, ranks better overall.

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.

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 0.60 years of 80.5, 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.
