Overall, American Canyon, California (ZIP 94503) lands in the top 11.6% healthiest ZIPs nationally (3,695th) and the top 25% of California (427th).
A number of measures place this area on solid footing: modeled obesity is in the bottom 5.7% nationally, and hearing disability settles in the bottom 6.4% nationally. Lead in tap water resides in the bottom 10.0% nationally, and park land registers in the top 10.1% nationally. Household income rests in the top 9.3% nationally, and modeled coronary heart disease stands in the bottom 8.7% nationally. Distance to a community health center lies at the national minimum, shared with about 23% of ZIPs. Modeled energy burden lands in the bottom 9.6% nationally. By contrast, modeled colon screening sits in the bottom 8.6% nationally, and crowded housing is in the top 10.8% nationally.
Set beside the nearby areas, park land runs far higher than the surrounding ZIPs on this measure. A note on the terms: lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. Distance to a community health center is a federally funded (HRSA) community health center serving everyone regardless of ability to pay. Energy burden is the share of household income that goes to home energy bills. For a healthier nearby comparison, ZIP 94547, about 8.3 miles away, ranks better 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 0.67 years of 80.3, 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
