ZIP 78633, one of several in Georgetown, Texas, by its composite score, sits in the top 8.7% healthiest ZIPs nationally (2,780th) and the top 4.9% of Texas (90th).
The data opens on a genuinely even set of readings: modeled colon screening registers in the top 0.4% nationally, and short sleep settles in the bottom 0.6% nationally. Modeled binge drinking sits in the bottom 1.6% nationally, and cognitive disability lies in the bottom 1.8% nationally. Modeled arsenic rests in the bottom 6.2% nationally, and tooth loss resides in the bottom 2.8% nationally. On the other side, modeled extreme heat is in the top 3.3% nationally, modeled high cholesterol lands in the top 2.1% nationally, and PFOA in drinking water stands in the top 5.5% nationally. PFOS in drinking water registers in the top 5.6% nationally.
Next to the surrounding area, park land runs far higher than the surrounding ZIPs on this measure. For anyone unfamiliar, PFOA in drinking water is one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. PFOS in drinking water is a common one of the man-made "forever chemicals" that build up in the body and environment instead of breaking down. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. For a healthier comparison close by, see ZIP 78681, about 4.7 miles away.

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. How distance is measured
