Full methodology ›The read
ZIP 93535, one of several in Lancaster, California, overall, ranks in the bottom 23% nationally (24,576th) and the bottom 19% of California (1,399th).
This area's pressures are easy to read across the measures: modeled colon screening lands in the bottom 2.2% nationally, modeled loneliness lies in the top 0.9% nationally, and outer-floodplain exposure stands in the top 3.3% nationally. Modeled arsenic rests in the top 3.4% nationally, housing insecurity registers in the top 3.8% nationally, and expected annual loss resides in the top 4.5% nationally. Modeled food insecurity settles in the top 5.7% nationally, and extreme heat is in the top 5.8% nationally. Modeled transportation sits in the top 6.2% nationally, and crowded housing lands in the top 6.3% nationally.
Measured against the nearby ZIPs, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. 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". ZIP 93534, 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 0.46 years of 75.5, 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
