Lower is healthier
ST99thUS98thDefinition & 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 ›Fatal road crashes

in the top 2.3% nationally
Lower is healthier
ST98thUS98thDefinition & source ›
The annual rate of fatal road crashes per 100,000 residents, pooled over a ten-year window.
A rate per resident population. Where a ZIP has too few residents for the rate to be reliable — about 30% of US ZIPs — no value is published rather than an unstable one; those ZIPs are absent from this comparison, not counted as crash-free.
Full methodology ›Slow internet speeds

Lower is healthier
ST97thUS96thDefinition & source ›
The share of homes whose fastest available download speed is under 10 Mbps.
Full methodology ›Grocery access

in the top 6.6% nationally
Higher is healthier
ST93rdUS93rdDefinition & source ›
The number of full supermarkets 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. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Crowded housing
7.8%
in the top 7.1% nationally
Lower is healthier
ST93rdUS93rdDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.

Lower is healthier
ST45thUS9thDefinition & 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.

The estimated share of women aged 50–74 who had a mammogram within the past two years.

The read
Overall, Zolfo Springs, Florida (ZIP 33890) lands in the bottom 22% nationally (24,946th) and the bottom 15% of Florida (826th).
A number of measures mark where this area is under strain: modeled uninsured sits in the top 2.4% nationally, and humid heat is in the top 0.6% nationally. Modeled disaster risk settles in the top 1.6% nationally, and fatal road crashes resides in the top 2.3% nationally. Slow internet speeds registers in the top 3.7% nationally, crowded housing rests in the top 7.1% nationally, and modeled tooth loss stands in the top 8.9% nationally. Modeled mammography lies in the bottom 8.6% nationally. On the brighter side, grocery lands in the top 6.6% nationally, and modeled arsenic sits in the bottom 8.6% nationally.
Set beside the nearby areas, slow internet speeds runs far higher than the surrounding ZIPs on this measure. A note on the terms: 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. For a healthier nearby comparison, ZIP 33852, just across the boundary, ranks better overall.

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 1.55 years of 77.9, 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.
