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.

What the numbers press hardest on defines much of the story here: modeled self-care disability stands in the top 3.3% nationally, floodplain exposure is in the top 1.6% nationally, and modeled stroke rests in the top 2.8% nationally. Modeled diabetes sits in the top 3.7% nationally, modeled independent living disability registers in the top 4.3% nationally, and distance to an emergency room lands in the top 2.8% nationally. Modeled mobility disability resides in the top 4.6% nationally, and vision disability lies in the top 6.0% nationally. On the encouraging side, pharmacy settles in the top 1.3% nationally, and outpatient stands in the top 4.2% nationally.

Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". ZIP 31331, just across the boundary, ranks healthier overall.

Findings that name this ZIP

One of our published findings lists this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.

  • Clean environment, heavy chronic burden

    Where the environment and chronic illness point in opposite directions

    Environmental-hazard standing 96.5 (top 10%); chronic-disease standing 3.9 (bottom 10%) — 93 points apart, cleaner on the environment than it is on chronic illness.

    Ranked #60 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 1.19 years of 77.0, 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.
