Key Facts
  • Larsen Bay has only 34 residents, making it one of Alaska's smallest communities with its own ZIP code
  • The community is 79% Native American, maintaining strong tribal identity on Kodiak Island's remote western shore
  • There's only one named street in the postal records (3rd Street), though one rural carrier route does serve the area
  • Eight businesses employ 23 people, meaning nearly 68% of the population works locally
  • The post office is the primary delivery infrastructure, with no city carrier routes in this isolated fishing village
  • Water area (75.4 sq mi) exceeds land area (17.8 sq mi) by more than 4 to 1, reflecting the community's coastal setting

Island Isolation

Larsen Bay sits on the western shore of Kodiak Island, one of Alaska's most isolated communities. The population of 34 makes this one of the smallest tribal communities in the state, where 79% of residents are Native American. The post office serves as the only address-based delivery option for the area.

Geographic Reality

The geography tells the story of isolation. Larsen Bay covers 17.8 square miles of land but sits adjacent to 75.4 square miles of water. There's no road connection to other Kodiak communities. Mail arrives by plane or ferry, making the post office the lifeline for 29 occupied households. One street route serves 3rd Street, but most residents rely on the post office for mail pickup.

Household Structure

Extended family households are common here. With 34 people in 29 homes, the ratio stays close to 1.2 people per household, typical for Alaska Native fishing villages where multiple generations often live together. The median age of 46.5 reflects a community that has retained its younger working-age population despite the challenges of remote living.

Fishing Economy

The economy revolves around commercial fishing. Eight businesses employ 23 people in this community of 34. That's an unusually high employment concentration for such a small population. The median household income of $44,375 reflects seasonal fishing earnings. During winter months when boats aren't running, the post office becomes one of the few public gathering points in town.

Street Name Patterns

Minimal Infrastructure Numbered Street

With just a single street in the postal database, Larsen Bay's infrastructure reflects its status as a tiny fishing village. The presence of 3rd Street suggests there may be 1st and 2nd Streets as well, but they don't appear in delivery records. Most residents get mail directly from the post office rather than through street delivery.
