San Ysidro, California (ZIP 92173), on the composite measure, lands in the bottom 39% nationally (19,541st) and the bottom 29% of California (1,212th).
Where this area is stretched, the data is unambiguous: modeled uninsured rests in the top 2.9% nationally, modeled colon screening sits in the bottom 2.8% nationally, and crowded housing registers in the top 1.1% nationally. Modeled loud transportation noise lands in the top 1.3% nationally, outer-floodplain exposure resides in the top 1.7% nationally, and modeled housing insecurity lies in the top 2.9% nationally. Modeled vision disability settles in the top 5.3% nationally, and transportation noise stands in the top 3.2% nationally. Housing-cost burden is in the top 3.6% nationally. Better still, subsidized affordable housing rests in the top 0.7% nationally.
Set against the neighboring ZIPs, subsidized affordable housing runs far higher than the surrounding ZIPs on this measure. In everyday language, subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". A healthier neighbor overall sits at ZIP 92154, just across the boundary.

Findings that name this ZIP
3 of our published findings list this ZIP code. Each finding compares one published measure against a stated benchmark, and names only the ZIP codes whose estimates are reliable enough to rank. See all surprising findings.
Above what income predicts
The ZIP codes that outlive their incomes
Estimated life expectancy is 81.7 ± 2.2 years. A median household income of $69,792 predicts 78.7 years — 3.0 years above.

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 1.11 years of 81.7, 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
