Health need and barriers to care documented here
On our reading, this ZIP code carries the overlap at its severe level: severe means at least four of the six health-need readings and at least four of the six access barriers apply to the same place.
These are two separate readings of public data that both apply to this place — never a claim that one causes the other, never a severity score, and never a statement about any person who lives here.
Health need documented here
- People without health insurance
- People living in poverty
- Food insecurity
- Housing insecurity
- Adults reporting fair or poor health
Barriers to reaching care
- Distance to the nearest emergency room
- Thin local supply of doctors
- Thin local supply of pharmacies
- Households with no vehicle
- Limited home internet for telehealth

A number of measures mark what daily life looks like here: modeled energy burden lies in the top 0.2% nationally, and tooth loss lands in the top 0.2% nationally. Modeled mammography sits in the bottom 0.2% nationally, and colon screening is in the bottom 0.3% nationally. Modeled vision disability settles in the top 1.2% nationally, independent living disability resides in the top 0.8% nationally, and cognitive disability registers in the top 0.6% nationally. Distance to an emergency room rests in the top 0.2% nationally.

Read against the ZIPs closest to it, childcare runs far higher than the surrounding ZIPs on this measure. To spell things out, 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. Close by, ZIP 99585, about 36 miles away, ranks healthier overall.

Nearby means closest by distance between ZIP boundaries, which can cross state lines. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

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.
