Walkability
1.3 intersections/sq mi
in the bottom 3.8% nationally
Higher is healthier
ST6thUS4thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Short sleep
28.4%
in the bottom 4.0% nationally
Lower is healthier
ST16thUS4thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Industrial-pollution burden
in the bottom 5.1% nationally
Lower is healthier
ST5thUS5thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Fine-particle (PM2.5) exceedance
1.7%
in the top 5.2% nationally
Lower is healthier
ST71stUS95thDefinition & 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 ›PFAS in drinking water
9.3%
in the bottom 7.5% nationally
Lower is healthier
ST14thUS7thDefinition & 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 ›Nitrate in drinking water
0.11%
in the top 8.2% nationally
Lower is healthier
ST91stUS92ndDefinition & source ›
The modeled share of this area’s domestic-well groundwater at or above the federal nitrate limit of 10 milligrams per liter.
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 ›Fatal road crashes
25.1 per 100,000 residents per year
in the top 19% nationally
Lower is healthier
ST90thUS81stDefinition & 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 ›Dry extreme heat
20 days/year
in the top 23% nationally
Lower is healthier
ST94thUS77thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.

Lower is healthier
ST6thUS35thDefinition & 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 ›The read
By the composite health measure, Waitsburg, Washington (ZIP 99361) ranks in the top 35% healthiest ZIPs nationally (11,296th) and the bottom 50% of Washington (291st), based on limited data; treat as directional.
The measures that set this area apart are worth putting up front: modeled short sleep resides in the bottom 4.0% nationally, and industrial-pollution burden registers in the bottom 5.1% nationally. Modeled pfas rests in the bottom 7.5% nationally, and humid heat stands in the bottom 13.2% nationally. Set against that, walkability lies in the bottom 3.8% nationally, modeled fine-particle lands in the top 5.2% nationally, and modeled nitrate sits in the top 8.2% nationally. Distance to a hazardous-chemical facility is at the national minimum, shared with about 31% of ZIPs. Recreation settles at the national minimum, shared with about 35% of ZIPs. Slow internet speeds resides in the top 18% nationally.
To spell things out, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. 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. Close by, ZIP 99143, about 7.6 miles away, ranks healthier 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. 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 1.22 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.
