ST93rdUS96thDefinition & 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.

The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.

ST99thUS95thDefinition & 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 ›The read
ZIP 97230, one of several in Portland, Oregon ranks in the bottom 27% nationally (23,456th) and the bottom 23% of Oregon (312th).
A number of readings press hard on the profile and set its tone: modeled air-toxics cancer risk registers in the top 0.9% nationally, and expected annual loss lies in the top 1.6% nationally. Modeled industrial-pollution burden is in the top 2.2% nationally, and disaster risk registers in the top 3.5% nationally. Modeled transportation noise lies in the top 4.5% nationally, floodplain exposure is in the top 4.7% nationally, and modeled loud transportation noise registers in the top 5.3% nationally. Distance to a Superfund site lies in the bottom 7.1% nationally. On the brighter side, transit is in the top 3.7% nationally, and park land registers in the top 7.4% nationally.
Against its neighbors, expected annual loss runs far higher than the surrounding ZIPs on this measure. For context, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. The closest ZIP that ranks healthier overall is ZIP 97024, just across the boundary.

Findings that name this ZIP
2 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.
Heavy environment, light chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 0.4 (bottom 1%); chronic-disease standing 59.5 — 59 points apart, heavier on the environment than it is on chronic illness.

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 0.47 years of 78.5, 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.
