Overall, ZIP 92703, one of several in Santa Ana, California places in the bottom 30% nationally (22,536th) and the bottom 23% of California (1,322nd).
The data opens on real and measurable burdens: modeled colon screening settles in the bottom 1.1% nationally, and crowded housing sits in the top 0.5% nationally. Modeled expected annual loss lies in the top 0.7% nationally, and uninsured rests in the top 3.3% nationally. Outer-floodplain exposure resides in the top 1.5% nationally, modeled loud transportation noise is in the top 2.9% nationally, and modeled fair or poor health lands in the top 4.9% nationally. Modeled loneliness stands in the top 4.0% nationally, and housing insecurity registers in the top 4.1% nationally. More encouragingly, walkability settles in the top 3.6% nationally.
Beside the areas that surround it, crowded housing runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Outer-floodplain exposure is land with a lower but real 1-in-500 chance of flooding each year, nicknamed the "500-year floodplain". 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. Among nearby ZIPs, the nearest healthier one overall is ZIP 92704, 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

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 0.58 years of 80.6, 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
