The Siassi Archipelago lies off the southeast coast of Umboi Island (a total of 18 islands, only seven are inhabited).
During the mid-1920s, the population of the Siassi Islands was a little over 700 people. It had more than doubled (to almost 1700 people) by the early 1960s, and then decreased to a little more than 1600 people by the early 1980s. The Siassi support themselves through traditional trade based on a barter system; they are important middlemen who deliver pigs, pots and wooden bowls by sea in their canoes.
