Full methodology ›The read
ZIP 63034, one of several in Florissant, Missouri, overall, ranks in the top 32% healthiest ZIPs nationally (10,136th) and the top 9.2% of Missouri (91st).
This area's most favorable readings come through plainly in the numbers: lead in tap water resides at the national minimum, park land settles in the top 6.5% nationally, and modeled mammography is in the top 7.1% nationally. Modeled colon screening sits in the top 9.2% nationally. Distance to a nursing home lands at the national minimum, shared with about 27% of ZIPs. On the other side, PFAS in drinking water lies at the national maximum, and modeled air-toxics cancer risk stands in the top 9.1% nationally. Floodplain exposure rests in the top 10.2% nationally, and lithium in drinking water registers in the top 13.2% nationally. Modeled high blood pressure resides in the top 12.7% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, lead in tap water is the EPA trigger, 15 parts per billion in tap samples, above which a water system must act on lead. PFAS in drinking water is the family of man-made "forever chemicals" that build up in the body and environment instead of breaking down. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. ZIP 62035, about 2.3 miles away, comes out healthier 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 0.74 years of 78.7, 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
