In overall standing, ZIP 77320, one of several in Huntsville, Texas comes out in the bottom 25% nationally (24,181st) and the bottom 37% of Texas (1,175th).
Both sides of the picture show up plainly in this area's numbers: distance to a community health center sits at the national minimum, shared with about 23% of ZIPs. Modeled radon settles in the bottom 5.2% nationally. By contrast, modeled uninsured registers in the top 4.9% nationally, and expected annual loss stands in the top 5.0% nationally. Modeled humid heat lands in the top 5.4% nationally, and short sleep is in the top 6.5% nationally. Modeled extreme heat resides in the top 6.3% nationally, and colon screening rests in the bottom 8.1% nationally. Housing-cost burden lies in the top 14.1% nationally, and unemployment sits in the top 15% nationally.
Relative to the ZIPs around it, expected annual loss runs far higher than the surrounding ZIPs on this measure. In plain terms, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. 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 77340, 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

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.
