Overall, ZIP 78664, one of several in Round Rock, Texas lands in the top 27% healthiest ZIPs nationally (8,743rd) and the top 14.2% of Texas (265th).
A handful of measures stand out most sharply across the profile here: subsidized affordable housing lands in the top 2.8% nationally, and modeled coronary heart disease sits in the bottom 5.1% nationally. Modeled hearing disability is in the bottom 6.4% nationally, and high cholesterol settles in the bottom 5.9% nationally. Modeled stroke resides in the bottom 6.7% nationally, and high blood pressure registers in the bottom 8.3% nationally. On the other side, modeled extreme heat rests in the top 3.2% nationally, expected annual loss stands in the top 6.9% nationally, and humid heat lies in the top 8.3% nationally. Modeled uninsured lands in the top 7.9% nationally.
Set beside the nearby areas, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. A note on the terms: expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. For a healthier nearby comparison, ZIP 78634, just across the boundary, ranks better 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 0.53 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.
