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 ›Humid extreme heat
6 days/year
in the bottom 3.8% nationally
Lower is healthier
ST29thUS4thDefinition & 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.

Lower is healthier
ST82ndUS96thDefinition & 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 ›The read
On the coverage assembled to date, for Marshall, Washington (ZIP 99020), health standing is not ranked here — the available data is too limited to place it confidently.
The measures that are covered come first, caveats noted: modeled expected annual loss settles in the bottom 1.6% nationally, and disaster risk lies in the bottom 2.3% nationally. Poverty resides at the national minimum, and homeownership lands at the national maximum. Home broadband subscription registers at the national maximum, floodplain exposure sits at the national minimum, and modeled humid heat rests in the bottom 3.8% nationally. By contrast, housing-cost burden is at the national maximum, modeled transportation noise stands in the top 1.0% nationally, and modeled fine-particle settles in the top 4.0% nationally.
Compared with the ZIPs it borders, transportation noise runs far higher than the surrounding ZIPs on this measure. In plainer terms, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard.

| Life expectancy at birth | 84.2 yr ± 1.86 | 78.9 yr (74.7–82.8) n=31,308 | 80.2 yr (77.3–83.1) n=584 |
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 1.86 years of 84.2, and it’s very unlikely to be off by more than twice that.
