In overall standing, ZIP 91911, one of several in Chula Vista, California comes out in the top 33% healthiest ZIPs nationally (10,632nd) and the top 48% of California (830th).
Both sides of the picture show up plainly in this area's numbers: subsidized affordable housing settles in the top 2.0% nationally. Distance to an emergency room registers at the national minimum, shared with about 11% of ZIPs. By contrast, crowded housing stands in the top 2.0% nationally, and housing-cost burden lands in the top 5.7% nationally. Modeled colon screening is in the bottom 6.6% nationally, and outer-floodplain exposure resides in the top 7.2% nationally. Modeled loneliness rests in the top 7.3% nationally, and housing insecurity lies in the top 7.3% nationally. Unemployment sits in the top 7.6% nationally, and modeled transportation noise settles in the top 7.8% nationally.
Relative to the ZIPs around it, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. In plain terms, subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels. The nearest healthier ZIP overall is ZIP 91910, 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 0.49 years of 81.4, 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
