By its overall health score, ZIP 95621, one of several in Citrus Heights, California lands in the bottom 46% nationally (17,425th) and the bottom 34% of California (1,127th).
Neither strongly one way nor the other, the measures sit mixed: walkability rests in the top 4.1% nationally, and subsidized affordable housing is in the top 10.3% nationally. Distance to a community health center stands at the national minimum, shared with about 23% of ZIPs. Against that, modeled air-toxics cancer risk settles in the top 0.6% nationally, fine-particle lies in the top 3.7% nationally, and extreme heat resides in the top 4.1% nationally. Modeled loud transportation noise lands in the top 4.1% nationally, tree cover registers at the national minimum, and loneliness sits in the top 7.3% nationally. Housing-cost burden rests in the top 10.0% nationally.
Weighed against the ZIPs nearby, park land runs far lower than the surrounding ZIPs on this measure. To translate a couple of terms, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Fine-particle is fine airborne particles about one-thirtieth the width of a hair, counted on modeled days above the EPA standard. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. Overall, the nearest healthier neighbor is ZIP 95608, just across the boundary.

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 0.59 years of 77.7, 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
