The read
ZIP 31404, one of several in Savannah, Georgia, overall, ranks in the bottom 37% nationally (20,117th) and the bottom 49% of Georgia (361st).
Reading across the data, the real pressures come first: modeled short sleep resides in the top 2.6% nationally, floodplain exposure settles in the top 3.7% nationally, and modeled loneliness is in the top 4.5% nationally. Outer-floodplain exposure sits in the top 5.6% nationally, modeled disaster risk lands in the top 6.0% nationally, and modeled expected annual loss lies in the top 8.2% nationally. Modeled humid heat stands in the top 8.3% nationally, and homeownership rests in the bottom 9.2% nationally. More encouragingly, subsidized affordable housing registers in the top 2.0% nationally. Distance to an emergency room resides at the national minimum, shared with about 11% of ZIPs.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, 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. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. ZIP 31401, just across the boundary, comes out healthier 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 0.68 years of 73.2, 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
