The read
By its overall health score, ZIP 77520, one of several in Baytown, Texas lands in the bottom 10.4% nationally (28,763rd) and the bottom 10.4% of Texas (1,675th).
The measures that press hardest set the tone here: modeled uninsured sits in the top 1.3% nationally, and industrial-pollution burden rests in the top 0.4% nationally. Modeled colon screening is in the bottom 2.9% nationally, and air-toxics cancer risk stands in the top 1.5% nationally. Outer-floodplain exposure settles in the top 3.4% nationally, modeled vision disability lies in the top 6.0% nationally, and distance to a Superfund site resides in the bottom 4.3% nationally. Modeled humid heat lands in the top 4.3% nationally, floodplain exposure registers in the top 4.4% nationally, and modeled expected annual loss sits in the top 4.8% nationally.
Weighed against the ZIPs nearby, industrial-pollution burden runs far lower than the surrounding ZIPs on this measure. To translate a couple of terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Overall, the nearest healthier neighbor is ZIP 77521, 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 1.1 (bottom 10%); chronic-disease standing 59.8 — 59 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 0.63 years of 76.7, 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.
