What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Floodplain exposure
63%
in the top 2.3% nationally
Lower is healthier
ST98thUS98thDefinition & 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 ›Industrial-pollution burden
in the top 3.0% nationally
Lower is healthier
ST91stUS97thDefinition & 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 ›Humid extreme heat
152.1 days/year
in the top 4.2% nationally
Lower is healthier
ST76thUS96thDefinition & 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 ›Physician access
2.4 per 1,000 residents
in the top 5.2% nationally
Higher is healthier
ST93rdUS95thDefinition & 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 ›Dental provider access
1.1 per 1,000 residents
in the top 5.3% nationally
Higher is healthier
ST95thUS95thDefinition & source ›
The number of dental 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 ›Radon
0.6 pCi/L
in the bottom 1.8% nationally
Lower is healthier
ST13thUS2ndDefinition & 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 ›Subsidized affordable housing
252 units
in the top 9.8% nationally
Higher is healthier
ST83rdUS90thDefinition & source ›
The number of affordable rental units in this ZIP supported by the federal Low-Income Housing Tax Credit program.
Full methodology ›Uninsured (under 65)

in the top 9.4% nationally
Lower is healthier
ST49thUS91stDefinition & source ›
The estimated share of adults aged 18–64 with no current health-insurance coverage.

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
Lake Jackson, Texas (ZIP 77566), by its composite score, sits in the bottom 49% nationally (16,381st) and the top 29% of Texas (544th).
The data opens on a genuinely even set of readings: physicians is in the top 5.2% nationally, and dental providers lands in the top 5.3% nationally. Distance to an emergency room stands at the national minimum, shared with about 11% of ZIPs. Modeled radon registers in the bottom 1.8% nationally, and subsidized affordable housing settles in the top 9.8% nationally. On the other side, floodplain exposure sits in the top 2.3% nationally, modeled industrial-pollution burden lies in the top 3.0% nationally, and modeled humid heat rests in the top 4.2% nationally. Modeled short sleep resides in the top 10.9% nationally, and outer-floodplain exposure is in the top 11.2% nationally.
Next to the surrounding area, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". For a healthier comparison close by, see ZIP 77583, about 11 miles away.

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 0.71 years of 79.2, 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.
