Full methodology ›The read
In overall standing, ZIP 77306, one of several in Conroe, Texas comes out in the bottom 17% nationally (26,773rd) and the bottom 22% of Texas (1,457th).
The data is direct about where this area carries real strain: modeled uninsured resides in the top 1.6% nationally, air-toxics cancer risk rests in the top 0.2% nationally, and colon screening lies in the bottom 3.4% nationally. Crowded housing sits in the top 2.7% nationally, modeled humid heat settles in the top 2.7% nationally, and modeled industrial-pollution burden registers in the top 3.3% nationally. Outer-floodplain exposure stands in the top 6.9% nationally, and modeled extreme heat lands in the top 9.1% nationally. Modeled mammography is in the bottom 11.0% nationally. More encouragingly, distance to a community health center resides at the national minimum, shared with about 23% of ZIPs.
Relative to the ZIPs around it, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. In plain terms, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. The nearest healthier ZIP overall is ZIP 77301, just across the boundary.

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 0.72 years of 74.6, 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
