The burdens that read clearest in the data come first: modeled mammography resides in the bottom 0.5% nationally, and energy burden lands in the top 0.7% nationally. Distance to a nursing home registers in the top 0.3% nationally, and distance to an emergency room sits in the top 0.5% nationally. Modeled hearing disability rests in the top 2.1% nationally, and distance to a community health center is in the top 1.7% nationally. Better still, distance to a hazardous-chemical facility stands in the top 0.4% nationally, housing-cost burden settles at the national minimum, and modeled transportation noise lies at the national minimum. Distance to a Superfund site resides in the top 2.3% nationally.

Compared with the ZIPs it borders, distance to a nursing home runs far higher than the surrounding ZIPs on this measure. In plainer terms, distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. Energy burden is the share of household income that goes to home energy bills. For a healthier nearby ZIP overall, look to ZIP 99756, about 11 miles away.

No data: Climate / Disaster Risk — not measured in this ZIP, so it is left out of the score entirely rather than estimated.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

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 0.81 years of 76.7, 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.
