Industrial-pollution burden
in the bottom 3.5% nationally
Lower is healthier
ST2ndUS3rdDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Recreation access
1.3 per 1,000 residents
in the top 4.9% nationally
Higher is healthier
ST89thUS95thDefinition & source ›
The number of places for physical recreation — gyms, sports, and fitness venues — 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
By the composite measure, Key Largo, Florida (ZIP 33037) sits in the top 20% healthiest ZIPs nationally (6,537th) and the top 26% of Florida (251st), based on limited data; treat as directional.
Reading across the measures, this area's clearest strengths come through: modeled industrial-pollution burden stands in the bottom 3.5% nationally, recreation is in the top 4.9% nationally, and modeled obesity rests in the bottom 8.0% nationally. Mental-health providers sits in the top 7.0% nationally, park land registers in the top 7.3% nationally, and outpatient lands in the top 7.7% nationally. Modeled extreme heat resides at the national minimum, shared with about 19% of ZIPs. Civic lies in the top 10.4% nationally. By contrast, modeled loud transportation noise settles in the top 5.9% nationally, and disaster risk stands in the top 7.9% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. ZIP 33070, just across the boundary, ranks 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 1.37 years of 80.8, 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.
