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.

Arsenic in groundwater

1.0%

in the bottom 2.1% nationally

Lower is healthier

ST9th
US2nd
Definition & 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.

Natural-disaster risk

in the top 2.7% nationally

Lower is healthier

ST99th
US97th
Definition & 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.

Full methodology ›

Physician access

3.3 per 1,000 residents

in the top 2.9% nationally

Higher is healthier

ST97th
US97th
Definition & source ›

The number of physicians’ offices located 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.

Slow internet speeds

4.0%

in the top 3.0% nationally

Lower is healthier

ST96th

Definition & source ›

The share of homes whose fastest available download speed is under 10 Mbps.

in the top 3.4% nationally

Higher is healthier

ST97th

Definition & source ›

The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.

Full methodology ›

Dental provider access

in the top 4.6% nationally

Higher is healthier

ST97th
US95th
Definition & source ›

The number of dental offices located 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.

Full methodology ›

Outer-floodplain exposure

8.2%

in the top 4.6% nationally

Lower is healthier

ST97th
US95th
Definition & 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 ›

Short sleep

43.5%

in the top 5.5% nationally

Lower is healthier

ST89th
US95th
Definition & source ›

The estimated share of adults who usually sleep less than seven hours in a 24-hour period.

ST96th
US93rd
Definition & 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.

in the top 7.1% nationally

Higher is healthier

ST93rd
US93rd
Definition & source ›

The number of outpatient clinics located inside this ZIP’s boundary, per 1,000 residents.

ZIP 31405, one of several in Savannah, Georgia, in overall standing, comes out in the bottom 47% nationally (17,010th) and the top 40% of Georgia (287th).

continue reading

A few readings each way define this mixed profile: modeled arsenic lands in the bottom 2.1% nationally, physicians rests in the top 2.9% nationally, and subsidized affordable housing settles in the top 3.4% nationally. Dental providers lands in the top 4.6% nationally, and outpatient rests in the top 7.1% nationally. Pulling the other way, modeled disaster risk settles in the top 2.7% nationally, and slow internet speeds lands in the top 3.0% nationally. Outer-floodplain exposure rests in the top 4.6% nationally, and modeled short sleep settles in the top 5.5% nationally. Modeled expected annual loss lands in the top 7.1% nationally.

Set within its surrounding area, slow internet speeds runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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. The closest healthier ZIP overall is ZIP 31322, just across the boundary.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.52 years of 75.8, and it’s very unlikely to be off by more than twice that.

More ZIPs to explore ▾

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. How distance is measured
