Humid extreme heat
187.5 days/year
in the top 1.2% nationally
Lower is healthier
ST61stUS99thDefinition & 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 ›PFAS in drinking water
64.1%
in the top 6.4% nationally
Lower is healthier
ST70thUS94thDefinition & source ›
The modeled probability that PFAS “forever chemicals” would be detected in untreated groundwater in this area, the source private wells draw on.
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 ›Uninsured (under 65)
17.3%
in the top 7.2% nationally

ST74thUS93rdDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.

Lower is healthier
ST90thUS92ndDefinition & 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 ›Floodplain exposure
32.7%
in the top 8.8% nationally
Lower is healthier
ST51stUS91stDefinition & 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 ›Arsenic in groundwater
1.3%
in the bottom 8.9% nationally
Lower is healthier
ST46thUS9thDefinition & 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 ›Short sleep

ST17thUS6thDefinition & 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 ›Obesity

The read
On balance, and by the composite measure, Auburndale, Florida (ZIP 33823) ranks in the bottom 22% nationally (25,135th) and the bottom 14.8% of Florida (830th).
Neither strongly one way nor the other, the measures sit mixed: modeled arsenic registers in the bottom 8.9% nationally, and radon sits in the bottom 5.6% nationally. Distance to a nursing home rests at the national minimum, shared with about 27% of ZIPs. Against that, modeled humid heat is in the top 1.2% nationally, pfas stands in the top 6.4% nationally, and uninsured settles in the top 7.2% nationally. Modeled disaster risk lies in the top 7.9% nationally, floodplain exposure resides in the top 8.8% nationally, and modeled short sleep lands in the top 9.2% nationally. Distance to a hazardous-chemical facility registers at the national minimum, shared with about 31% of ZIPs.
In plainer terms, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. For a healthier nearby ZIP overall, look to ZIP 33850, just across the boundary.

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 0.49 years of 75.9, 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. How distance is measured
