Full methodology ›The read
With the picture still incomplete, for Arlington, Colorado (ZIP 81021), health standing is not ranked here — the available data is too limited to place it confidently.
Where the data does reach, it says a few things here: modeled transportation noise sits at the national minimum, and air-toxics cancer risk registers in the bottom 2.8% nationally. Set against that, poverty lands in the top 0.6% nationally, walkability resides in the bottom 0.6% nationally, and housing-cost burden lies in the top 1.0% nationally. Slow internet speeds settles in the top 1.9% nationally, and home broadband subscription stands in the bottom 3.4% nationally. Modeled nitrate is in the top 3.8% nationally, and tree cover rests at the national minimum. Distance to an emergency room sits in the top 5.6% nationally.
Set against the neighboring ZIPs, slow internet speeds runs far higher than the surrounding ZIPs on this measure. In everyday language, air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Nitrate is a groundwater compound from fertilizer, manure, and sewage, here a modeled estimate of the chance private-well levels exceed a benchmark. Transportation noise is the modeled share of an area exposed to average road, rail, and air noise at or above 55 decibels.

| Life expectancy at birth | 78.2 yr ± 0.86 | 78.9 yr (74.7–82.8) n=31,308 | 80.4 yr (76.8–83.2) n=466 |
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 0.86 years of 78.2, and it’s very unlikely to be off by more than twice that.
