Home broadband subscription

ST9thUS7thDefinition & source ›
The share of households with a broadband internet subscription.

Lower is healthier
ST92ndUS92ndDefinition & 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 ›Radon
2.8 pCi/L
in the top 14.4% nationally
Lower is healthier
ST96thUS86thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Arsenic in groundwater
9.0%
in the top 20% nationally
Lower is healthier
ST98thUS80thDefinition & 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 its overall standing, Amazonia, Missouri (ZIP 64421) lands in the bottom 16% nationally (26,826th) and the bottom 29% of Missouri (704th).
This area's measures are easy to read as a mixed set: distance to a Superfund site resides in the top 12.3% nationally, and households without a vehicle settles in the bottom 16% nationally. Set against that, home broadband subscription is in the bottom 6.9% nationally, floodplain exposure sits in the top 8.3% nationally, and modeled cognitive disability lands in the top 11.6% nationally. Modeled radon lies in the top 14.4% nationally, and loud transportation noise stands in the top 14.7% nationally. Modeled transportation noise rests in the top 14.8% nationally. Distance to a hazardous-chemical facility registers at the national minimum, shared with about 31% of ZIPs. Modeled mammography resides in the bottom 14.9% nationally.
Against the wider neighborhood, park land runs far lower than the surrounding ZIPs on this measure. Put simply, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. 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. On the overall standing, ZIP 64473, just across the boundary, ranks healthier.

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 1.32 years of 78.9, 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.
