The read
By the composite health measure, ZIP 77099, one of several in Houston, Texas ranks in the bottom 14.7% nationally (27,380th) and the bottom 18% of Texas (1,541st).
Where the load on this area runs deepest, the data leads: modeled uninsured sits in the top 1.3% nationally, and colon screening is in the bottom 1.4% nationally. Outer-floodplain exposure settles in the top 1.4% nationally, and modeled vision disability resides in the top 4.1% nationally. Crowded housing registers in the top 2.0% nationally, modeled short sleep rests in the top 3.4% nationally, and modeled humid heat stands in the top 3.3% nationally. Modeled mammography lies in the bottom 4.4% nationally, and housing-cost burden lands in the top 3.9% nationally. More encouragingly, subsidized affordable housing sits in the top 1.6% nationally.
Read against the ZIPs closest to it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. To spell things out, outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. Close by, ZIP 77072, just across the boundary, ranks healthier overall.

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 0.67 years of 77.9, 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.
