Full methodology ›The read
ZIP 77338, one of several in Humble, Texas, on the composite measure, lands in the bottom 38% nationally (19,920th) and the top 41% of Texas (759th).
What the numbers press hardest on defines much of the story here: modeled uninsured resides in the top 3.7% nationally, industrial-pollution burden lies in the top 1.4% nationally, and humid heat settles in the top 2.8% nationally. Outer-floodplain exposure stands in the top 2.9% nationally, modeled expected annual loss is in the top 3.1% nationally, and modeled short sleep rests in the top 5.1% nationally. Modeled air-toxics cancer risk sits in the top 4.5% nationally, and colon screening registers in the bottom 5.6% nationally. On the encouraging side, subsidized affordable housing lands in the top 4.2% nationally. Distance to an emergency room resides at the national minimum, shared with about 11% of ZIPs.
Set against the neighboring ZIPs, industrial-pollution burden 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. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. A healthier neighbor overall sits at ZIP 77339, just across the boundary.

Findings that name this ZIP
2 of our published findings list 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.
Heavy environment, light chronic burden
Where the environment and chronic illness point in opposite directions
Environmental-hazard standing 14.6; chronic-disease standing 78.7 — 64 points apart, heavier on the environment than it is on chronic illness.

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 0.76 years of 78.7, 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. How distance is measured
