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.
Transit access
7.7 per 1,000 residents
in the top 2.2% nationally
Higher is healthier
ST98thUS98thDefinition & source ›
The number of public-transit stops 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 ›PFAS in drinking water
75%
in the top 3.1% nationally
Lower is healthier
ST92ndUS97thDefinition & 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 ›Energy-cost burden
0.98%
in the bottom 0.9% nationally
Lower is healthier
ST6thUS1stDefinition & 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 ›Walkability
1.6 intersections/sq mi
in the bottom 5.1% nationally
Higher is healthier
ST10thUS5thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Loud transportation noise
2.5%
in the top 5.4% nationally
Lower is healthier
ST96thUS95thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›Crowded housing
9.1%
in the top 5.4% nationally
Lower is healthier
ST93rdUS95thDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.
Full methodology ›Short sleep
28.6%
in the bottom 4.6% nationally
Lower is healthier
ST18thUS5thDefinition & source ›
The estimated share of adults who usually sleep less than seven hours in a 24-hour period.
Full methodology ›Fine-particle (PM2.5) exceedance
1.4%
in the top 6.4% nationally
Lower is healthier
ST68thUS94thDefinition & 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
68.4%
in the bottom 8.6% nationally
Higher is healthier
ST17thUS9thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Arsenic in groundwater
15.6%
in the top 9.5% nationally
Lower is healthier
ST83rdUS91stDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms 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 ›The read
In overall standing, Rock Island, Washington (ZIP 98850) comes out in the top 27% healthiest ZIPs nationally (8,785th) and the top 37% of Washington (217th), based on limited data; treat as directional.
The profile opens balanced, with readings on either hand: transit registers in the top 2.2% nationally, modeled energy burden stands in the bottom 0.9% nationally, and modeled short sleep lands in the bottom 4.6% nationally. By contrast, modeled pfas is in the top 3.1% nationally, walkability resides in the bottom 5.1% nationally, and modeled loud transportation noise rests in the top 5.4% nationally. Crowded housing lies in the top 5.4% nationally, and modeled fine-particle sits in the top 6.4% nationally. Modeled mammography settles in the bottom 8.6% nationally, and arsenic registers in the top 9.5% nationally.
In plain terms, 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. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. The nearest healthier ZIP overall is ZIP 98802, just across the boundary.

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 1.70 years of 81.5, 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.
