Floodplain exposure
50.6%
in the top 3.9% nationally
Lower is healthier
ST76thUS96thDefinition & source ›
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.

2 per 1,000 residents
in the top 7.4% nationally
Higher is healthier
ST79thUS93rdDefinition & source ›
The number of physicians’ offices located 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.
Full methodology ›The read
ZIP 33777, one of several in Seminole, Florida, on the composite measure, lands in the top 23% healthiest ZIPs nationally (7,409th) and the top 31% of Florida (298th).
What works most in this area's favor shows up clearly across the measures: physicians registers in the top 7.4% nationally. Modeled extreme heat lands at the national minimum, shared with about 19% of ZIPs. Distance to a nursing home resides at the national minimum, shared with about 27% of ZIPs. Modeled obesity lies in the bottom 14.8% nationally, and walkability settles in the top 14.4% nationally. Distance to an emergency room stands in the bottom 14.5% nationally, and pharmacy is in the top 15% nationally. Modeled energy burden rests in the bottom 14.2% nationally. Working the other way, floodplain exposure sits in the top 3.9% nationally, and modeled industrial-pollution burden registers in the top 12.1% nationally.
Set against the neighboring ZIPs, park land runs far higher than the surrounding ZIPs on this measure. In everyday language, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. A healthier neighbor overall sits at ZIP 33708, 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 0.94 years of 78.2, 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.
