What defines this ZIP

Industrial-pollution burden
in the bottom 0.2% nationally
Lower is healthier
ST1stUS1stDefinition & 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 ›Fatal road crashes
79.3 per 100,000 residents per year
in the top 1.0% nationally
Lower is healthier
ST99thUS99thDefinition & 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 ›Fine-particle (PM2.5) exceedance
3.8%
in the top 1.6% nationally
Lower is healthier
ST97thUS98thDefinition & 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 ›Mammography
66.1%
in the bottom 4.1% nationally
Higher is healthier
ST7thUS4thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Child-care access
0.8 per 1,000 residents
in the top 3.9% nationally
Higher is healthier
ST98thUS96thDefinition & source ›
The number of child day-care services 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 ›Crowded housing
10.5%
in the top 4.2% nationally
Lower is healthier
ST95thUS96thDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.
Full methodology ›Home broadband subscription

in the bottom 4.4% nationally
Higher is healthier
ST2ndUS4thDefinition & source ›
The share of households with a broadband internet subscription.
Full methodology ›Distance to a hazardous-chemical facility
16.5 mi
in the top 6.9% nationally
Higher is healthier
ST92ndUS93rdDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest facility that handles enough hazardous chemicals to require an EPA risk-management plan for accidental releases.
Full methodology ›Slow internet speeds
1.6%
in the top 7.1% nationally
Lower is healthier
ST91stUS93rdDefinition & source ›
The share of homes whose fastest available download speed is under 10 Mbps.
Full methodology ›Poverty rate

Full methodology ›The read
On the composite measure, Nespelem, Washington (ZIP 99155) stands in the bottom 19% nationally (25,876th) and the bottom 3.3% of Washington (562nd), based on limited data; treat as directional.
A number of readings press hard on the profile and set its tone: fatal road crashes resides in the top 1.0% nationally, and modeled fine-particle stands in the top 1.6% nationally. Modeled mammography sits in the bottom 4.1% nationally, and crowded housing resides in the top 4.2% nationally. Home broadband subscription stands in the bottom 4.4% nationally, slow internet speeds sits in the top 7.1% nationally, and poverty resides in the top 8.3% nationally. On the brighter side, modeled industrial-pollution burden stands in the bottom 0.2% nationally, childcare sits in the top 3.9% nationally, and distance to a hazardous-chemical facility resides in the top 6.9% nationally.
For clarity, 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. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. ZIP 98840, 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 3.65 years of 88.2, 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.
