Total tribal membership was at 1,022 as of 2010. Tribal members no longer reside on Squaxin Island itself, but 509 residents live on other Reservation and Off-Reservation Trust Land. Today, the reservation also includes several small parcels in the nearby area. The Reservation was created in 1854 by the Treaty of Medicine Creek, comprising the entirety of Squaxin Island. Historically, the ancestors of the Squaxin Island Tribe inhabited several inlets of the South Puget Sound. The Squaxin Island Tribe are the descendants of several Lushootseed clans organized under the Squaxin Island Indian Reservation, a Native American tribal government in western Washington state.
