Calexico, California (ZIP 92231), overall, ranks in the bottom 17% nationally (26,495th) and the bottom 13.3% of California (1,491st).
This area's pressures are easy to read across the measures: modeled extreme heat is in the top 0.02% nationally, vision disability sits in the top 2.2% nationally, and uninsured lands in the top 2.7% nationally. Modeled colon screening lies in the bottom 2.5% nationally, modeled fair or poor health stands in the top 2.5% nationally, and unemployment rests in the top 2.1% nationally. Modeled humid heat registers in the top 2.5% nationally, and self-care disability resides in the top 5.1% nationally. Modeled housing insecurity settles in the top 3.5% nationally. On the brighter side, subsidized affordable housing is in the top 1.0% nationally.
Measured against the nearby ZIPs, subsidized affordable housing runs far higher than the surrounding ZIPs on this measure. Defined simply, extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. Humid heat is a modeled heat-stress measure combining temperature, humidity, sun, and wind to gauge heat on the body outdoors. ZIP 92243, just across the boundary, comes out healthier 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 0.69 years of 82.2, 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
