Humid extreme heat
163.1 days/year
in the top 2.6% nationally
Lower is healthier
ST18thUS97thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Arsenic in groundwater
1.3%
in the bottom 9.2% nationally
Lower is healthier
ST48thUS9thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Floodplain exposure
31.5%
in the top 9.3% nationally
Lower is healthier
ST48thUS91stDefinition & 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.
Full methodology ›Crowded housing
6.5%
in the top 9.5% nationally
Lower is healthier
ST89thUS91stDefinition & source ›
The share of occupied homes with more than one person per room, the Census definition of crowded housing.
Full methodology ›Radon
0.8 pCi/L
in the bottom 7.5% nationally
Lower is healthier
ST24thUS7thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Unemployment rate
1.3%
in the bottom 21% nationally
Lower is healthier
ST8thUS21stDefinition & source ›
The share of the civilian labor force that is unemployed.
Full methodology ›Distance to a community health center

Lower is healthier
ST95thUS75thDefinition & source ›
The distance in miles from this ZIP’s edge to the nearest federally funded community health center, which serves patients regardless of ability to pay.

Combined exposures in this ZIP
More than one environmental exposure stands out in this ZIP. Each is established independently and shown on its own above; they are grouped here for context — not because one causes the other.
This area ranks among the highest 10% of US ZIP codes for both humid-heat days and flood exposure.

The read
Glen St. Mary, Florida (ZIP 32040), by its composite score, sits in the bottom 29% nationally (22,790th) and the bottom 22% of Florida (757th).
The measures land in both directions, and neither dominates: modeled arsenic lies in the bottom 9.2% nationally, and radon rests in the bottom 7.5% nationally. Grocery resides in the top 15% nationally, and modeled industrial-pollution burden is in the bottom 17% nationally. Unemployment lands in the bottom 21% nationally. Pulling the other way, modeled humid heat stands in the top 2.6% nationally, floodplain exposure registers in the top 9.3% nationally, and crowded housing settles in the top 9.5% nationally. Fatal road crashes sits in the top 13.2% nationally. Recreation lies at the national minimum, shared with about 35% of ZIPs.
For anyone unfamiliar, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby.

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 0.77 years of 76.4, 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.
