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.
Transportation noise
100%
at the national maximum
Lower is healthier
ST99thUS99thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 55 decibels — a noticeable background presence.
Full methodology ›Outer-floodplain exposure
27.8%
in the top 1.5% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 0.2%-annual-chance flood band — the “500-year” zone, a lower but real 1-in-500 yearly chance.
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 ›Industrial-pollution burden
in the top 2.2% nationally
Lower is healthier
ST97thUS98thDefinition & source ›
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 ›Air-toxics cancer risk
40 per million
in the top 4.5% nationally
Lower is healthier
ST94thUS96thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›Tree cover
0.00%
at the national minimum
Higher is healthier
ST1stUS1stDefinition & source ›
The share of this ZIP’s land area covered by forest.
Full methodology ›Distance to a Superfund site
1.6 mi
in the bottom 9.5% nationally
Higher is healthier
ST7thUS9thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest Superfund site — an abandoned or uncontrolled hazardous-waste site the EPA has listed for cleanup.
Full methodology ›Floodplain exposure
28%
in the top 11.1% nationally
Lower is healthier
ST94thUS89thDefinition & 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 ›Walkability
76 intersections/sq mi
in the top 14.6% nationally
Higher is healthier
ST92ndUS85thDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Humid extreme heat
117.6 days/year
in the top 14.6% nationally
Lower is healthier
ST97thUS85thDefinition & 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.
Full methodology ›Dry extreme heat
25.4 days/year
in the top 19% nationally
Lower is healthier
ST99thUS81stDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›The read
Working only from the data in hand, for ZIP 38131, one of several in Memphis, Tennessee, health standing is not ranked here — the available data is too limited to place it confidently.
What little the measures show is worth setting out plainly: walkability registers in the top 14.6% nationally. On the other hand, modeled transportation noise sits at the national maximum, and outer-floodplain exposure rests in the top 1.5% nationally. Modeled industrial-pollution burden is in the top 2.2% nationally, air-toxics cancer risk stands in the top 4.5% nationally, and tree cover settles at the national minimum. Distance to a Superfund site lies in the bottom 9.5% nationally. Fiber broadband resides at the national minimum, shared with about 19% of ZIPs. Floodplain exposure lands in the top 11.1% nationally, and modeled humid heat registers in the top 14.6% nationally.
Weighed against the ZIPs nearby, transportation noise runs far higher than the surrounding ZIPs on this measure. To translate a couple of terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup.

|---|---|---|---|
| Life expectancy at birth | 72.4 yr ± 1.16 | 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 1.16 years of 72.4, and it’s very unlikely to be off by more than twice that.
