The number of places for physical recreation — gyms, sports, and fitness venues — inside this ZIP’s boundary, per 1,000 residents.

Full methodology ›The read
ZIP 94063, one of several in Redwood City, California, in overall standing, comes out in the top 30% healthiest ZIPs nationally (9,752nd) and the top 46% of California (788th).
A balanced showing across the data, with a few readings each side: modeled high blood pressure stands in the bottom 2.8% nationally, and recreation resides in the top 4.6% nationally. On the other hand, crowded housing sits in the top 1.4% nationally, modeled loud transportation noise stands in the top 1.8% nationally, and modeled expected annual loss resides in the top 1.8% nationally. Floodplain exposure sits in the top 2.4% nationally, and homeownership stands in the bottom 3.4% nationally. Outer-floodplain exposure resides in the top 3.6% nationally, and modeled transportation noise sits in the top 3.7% nationally. Modeled colon screening stands in the bottom 5.1% nationally.
Set within its surrounding area, outer-floodplain exposure runs far higher than the surrounding ZIPs on this measure. Defined simply, for reference, 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. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". The closest healthier ZIP overall is ZIP 94025, 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 0.75 years of 79.7, 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
