The modeled share of household income spent on home energy bills — electricity, gas, and heating fuels.
A modeled share of household income spent on home energy. Estimates that hit the model’s 100% ceiling are suppressed rather than published, because at that point the figure reflects the model’s limit rather than a measured burden.
Full methodology ›The read
By the composite health measure, ZIP 37405, one of several in Chattanooga, Tennessee ranks in the top 30% healthiest ZIPs nationally (9,486th) and the top 7.0% of Tennessee (43rd).
The picture here is genuinely mixed, with readings on both sides: mental-health providers settles in the top 2.4% nationally, and recreation resides in the top 6.6% nationally. Fiber broadband registers in the top 7.6% nationally, and modeled tree cover rests in the top 7.7% nationally. Transit stands in the top 9.7% nationally, outpatient lies in the top 10.0% nationally, and modeled energy burden lands in the bottom 8.5% nationally. On the other side, homeownership sits in the bottom 8.4% nationally, distance to a Superfund site is in the bottom 8.8% nationally, and modeled air-toxics cancer risk settles in the top 8.9% nationally.
Read against the ZIPs closest to it, park land runs far higher than the surrounding ZIPs on this measure. To spell things out, distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Air-toxics cancer risk is a modeled EPA estimate of added lifetime cancer risk from breathing outdoor air, per million people. Energy burden is the share of household income that goes to home energy bills. Close by, ZIP 37377, just across the boundary, ranks 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 0.84 years of 78.1, 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
