Full methodology ›The read
In its overall standing, ZIP 77031, one of several in Houston, Texas lands in the bottom 17% nationally (26,523rd) and the bottom 23% of Texas (1,430th).
This area's pressures are easy to read across the measures: modeled uninsured sits in the top 0.8% nationally, vision disability lands in the top 3.0% nationally, and colon screening lies in the bottom 3.6% nationally. Outer-floodplain exposure stands in the top 2.3% nationally, modeled industrial-pollution burden rests in the top 3.0% nationally, and modeled humid heat registers in the top 3.5% nationally. Modeled self-care disability resides in the top 5.4% nationally, and housing-cost burden settles in the top 4.2% nationally. Modeled air-toxics cancer risk is in the top 4.5% nationally, and crowded housing sits in the top 4.7% nationally.
Against the wider neighborhood, park land runs far lower than the surrounding ZIPs on this measure. Put simply, 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. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". On the overall standing, ZIP 77071, just across the boundary, ranks healthier.

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 0.97 years of 78.0, 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.
