Full methodology ›The read
By the composite measure, ZIP 93311, one of several in Bakersfield, California sits in the top 24% healthiest ZIPs nationally (7,541st) and the top 40% of California (685th).
The readings split fairly evenly between strengths and concerns: modeled hearing disability rests in the bottom 5.0% nationally, coronary heart disease sits in the bottom 5.7% nationally, and high blood pressure registers in the bottom 5.6% nationally. Park land lands in the top 7.6% nationally, and modeled high cholesterol resides in the bottom 6.1% nationally. Working the other way, modeled extreme heat lies in the top 0.7% nationally, and fine-particle settles in the top 1.2% nationally. Modeled nitrate stands in the top 5.6% nationally, and humid heat is in the top 6.3% nationally. Modeled air-toxics cancer risk rests in the top 8.0% nationally.
Compared with the ZIPs that surround it, park land runs far higher than the surrounding ZIPs on this measure. In plain language, fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. ZIP 93040, about 9.8 miles away, ranks healthier overall.

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.
Below what income predicts
The ZIP codes that outlive their incomes
Estimated life expectancy is 79.2 ± 0.8 years. A median household income of $116,263 predicts 80.7 years — 1.5 years below.

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 0.43 years of 79.2, 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
