Higher is healthier
ST95thUS95thDefinition & 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.”

Overall, Altha, Florida (ZIP 32421) places in the bottom 18% nationally (26,221st) and the bottom 11.8% of Florida (860th).
The data opens on a genuinely even set of readings: distance to a hazardous-chemical facility lands in the top 3.7% nationally, and grocery stands in the top 5.4% nationally. On the other side, modeled humid heat registers in the top 3.4% nationally, and distance to an emergency room settles in the top 6.9% nationally. Fiber broadband sits at the national minimum, shared with about 19% of ZIPs. Modeled mammography lies in the bottom 10.7% nationally, crowded housing rests in the top 12.5% nationally, and floodplain exposure resides in the top 17% nationally. Modeled high cholesterol is in the top 13.1% nationally, and slow internet speeds lands in the top 17% nationally.
For readers new to these terms, 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. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Among nearby ZIPs, the nearest healthier one overall is ZIP 32466, 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 1.16 years of 77.6, 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.
