Walkability
0.067 intersections/sq mi
in the bottom 0.4% nationally
Higher is healthier
ST16thUS1stDefinition & source ›
The number of street intersections per square mile — a standard street-connectivity measure; denser networks correlate with more walkable neighborhoods.
Full methodology ›Park land

in the top 0.8% nationally
Higher is healthier
ST95thUS99thDefinition & source ›
The share of this ZIP’s land area that is public parkland.
Full methodology ›Natural-disaster risk
in the top 2.3% nationally
Lower is healthier
ST95thUS98thDefinition & source ›
This area’s national rank on its single highest non-flood natural hazard — such as wildfire, tornado, or earthquake — in FEMA’s modeled National Risk Index; flooding is shown separately.
Full methodology ›Energy-cost burden
5.8%
in the top 3.7% nationally
Lower is healthier
ST33rdUS96thDefinition & source ›
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 ›Air-toxics cancer risk
10.6 per million

Lower is healthier
ST86thUS5thDefinition & source ›
The EPA’s modeled estimate of added lifetime cancer risk from breathing outdoor air toxics, in cases per million people exposed over a lifetime.
Full methodology ›Child-care access

in the top 7.5% nationally
Higher is healthier
ST87thUS93rdDefinition & source ›
The number of child day-care services inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one.

Full methodology ›The read
Judged by its overall standing, Petersburg, Alaska (ZIP 99833) sits in the top 32% healthiest ZIPs nationally (10,272nd) and the top 17% of Alaska (35th), based on limited data; treat as directional.
A few readings each way define this mixed profile: park land sits in the top 0.8% nationally, modeled air-toxics cancer risk stands in the bottom 5.5% nationally, and childcare resides in the top 7.5% nationally. Distance to a Superfund site sits in the top 8.7% nationally, civic stands in the top 10.0% nationally, and recreation resides in the top 11.5% nationally. Pulling the other way, walkability sits in the bottom 0.4% nationally, and modeled disaster risk stands in the top 2.3% nationally. Modeled energy burden resides in the top 3.7% nationally, and slow internet speeds sits in the top 10.2% nationally.
Placed beside its immediate neighbors, park land runs far higher than the surrounding ZIPs on this measure. Put plainly, 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. Distance to a Superfund site is an abandoned or uncontrolled hazardous-waste site the EPA has identified for cleanup. A healthier nearby ZIP overall is ZIP 99835, about 12 miles away.

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 1.18 years of 82.3, 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.
