Fiber broadband
100%

Higher is healthier
ST99thUS99thDefinition & source ›

ST1stUS1stDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.

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.

Lower is healthier
ST2ndUS4thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.

ST3rdUS9thDefinition & source ›
FEMA’s modeled estimate, in dollars per year, of the average harm to people expected from natural hazards — an annualized average, not a forecast for any single year.

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 ›The read
On the limited readings gathered so far, for Crockett Mills, Tennessee (ZIP 38021), health standing is not ranked here — the available data is too limited to place it confidently.
On the measures in hand, a few readings come through: fiber broadband lands at the national maximum, modeled transportation noise rests at the national minimum, and floodplain exposure settles at the national minimum. Modeled disaster risk lands in the bottom 4.0% nationally, and expected annual loss rests in the bottom 9.0% nationally. Modeled loud transportation noise settles at the national minimum, shared with about 22% of ZIPs. Distance to a hazardous-chemical facility lands in the top 14.1% nationally. Outer-floodplain exposure rests at the national minimum, shared with about 36% of ZIPs. Against that, distance to an emergency room settles in the top 9.7% nationally, and distance to a community health center lands in the top 13.8% nationally.
Put plainly, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. 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.

|---|---|---|---|
| Life expectancy at birth | 74.1 yr ± 0.86 | 78.9 yr (74.7–82.8) n=31,308 | 75.1 yr (72.6–78.1) n=587 |
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 0.86 years of 74.1, and it’s very unlikely to be off by more than twice that.
