The read

ZIP 95377, one of several in Tracy, California, on the composite measure, lands in the top 12.3% healthiest ZIPs nationally (3,928th) and the top 26% of California (446th).

continue reading

The readings split fairly evenly between strengths and concerns: household income lands in the top 3.1% nationally, modeled hearing disability resides in the bottom 3.2% nationally, and modeled high blood pressure lies in the bottom 4.2% nationally. Modeled coronary heart disease settles in the bottom 4.1% nationally, and obesity stands in the bottom 7.8% nationally. Working the other way, modeled pfas is in the top 3.4% nationally, and colon screening rests in the bottom 4.8% nationally. Modeled nitrate sits in the top 5.5% nationally, and disaster risk registers in the top 6.2% nationally. Distance to a Superfund site lands in the bottom 7.5% nationally.

In everyday language, pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. A healthier neighbor overall sits at ZIP 94550, just across the boundary.

Findings that name this ZIP

2 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 79.6 ± 1.2 years. A median household income of $158,158 predicts 81.9 years — 2.3 years below.

    Ranked #3,105 of the 5,842 ZIP codes this finding names, ordered by years above what income predicts, highest first.

  • Heavy environment, light chronic burden

    Where the environment and chronic illness point in opposite directions

    Environmental-hazard standing 23.7; chronic-disease standing 96.3 (top 10%) — 73 points apart, heavier on the environment than it is on chronic illness.

    Ranked #16,623 of the 18,187 ZIP codes this finding names, ordered by the gap from cleanest environment to heaviest chronic burden, highest first.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.61 years of 79.6, 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.
