ZIP 80233, one of several in Thornton, Colorado, overall, ranks in the top 32% healthiest ZIPs nationally (10,176th) and the bottom 49% of Colorado (258th).
This area's most favorable readings come through plainly in the numbers: subsidized affordable housing lands in the top 3.4% nationally, modeled high cholesterol lies in the bottom 4.3% nationally, and modeled high blood pressure stands in the bottom 4.8% nationally. Walkability rests in the top 8.0% nationally, and park land registers in the top 8.3% nationally. On the other side, modeled disaster risk resides in the top 4.2% nationally, and air-toxics cancer risk settles in the top 4.5% nationally. Modeled tree cover is at the national minimum, and mammography sits in the bottom 7.0% nationally. Modeled expected annual loss lands in the top 7.0% nationally.
Measured against the nearby ZIPs, park land runs far higher than the surrounding ZIPs on this measure. Defined simply, disaster risk is the area's national rank on its highest non-flood peril in FEMA's modeled Risk Index, like wildfire or quake. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. ZIP 80234, just across the boundary, 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 0.76 years of 77.8, 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.
