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 ›The read
ZIP 29678, one of several in Seneca, South Carolina ranks in the bottom 32% nationally (21,874th) and the bottom 43% of South Carolina (237th).
A balanced set of signals defines this area, not any single one: subsidized affordable housing lies in the top 6.3% nationally, and physicians is in the top 7.6% nationally. Mental-health providers registers in the top 8.2% nationally, and outpatient lies in the top 9.0% nationally. Grocery is in the top 9.6% nationally. Distance to a community health center registers at the national minimum, shared with about 23% of ZIPs. Distance to an emergency room lies in the bottom 12.1% nationally. By contrast, modeled expected annual loss is in the top 7.9% nationally, air-toxics cancer risk registers in the top 9.1% nationally, and disaster risk lies in the top 10.3% nationally.
For context, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. The closest ZIP that ranks healthier overall is ZIP 29625, 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 0.53 years of 76.0, 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
