In its overall standing, Winnetka, California (ZIP 91306) lands in the top 39% healthiest ZIPs nationally (12,592nd) and the bottom 47% of California (904th).
Taken together, the data gives a genuinely mixed reading: modeled obesity stands in the bottom 8.5% nationally, walkability rests in the top 7.1% nationally, and subsidized affordable housing registers in the top 8.7% nationally. On the other side, modeled colon screening resides in the bottom 2.8% nationally, modeled loneliness settles in the top 2.4% nationally, and crowded housing is in the top 2.7% nationally. Housing-cost burden sits in the top 3.7% nationally, and modeled expected annual loss lands in the top 4.2% nationally. Modeled tree cover lies at the national minimum, and loud transportation noise stands in the top 7.6% nationally.
Against the wider neighborhood, park land runs far lower than the surrounding ZIPs on this measure. Put simply, expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Subsidized affordable housing is the main federal tax-credit program (HUD) funding affordable rental housing, counted as local units it supports. On the overall standing, ZIP 91304, just across the boundary, ranks healthier.

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 0.60 years of 81.6, 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. How distance is measured
