The local economy is based primarily on agriculture, which employs a majority of the resident population. Most residents of smaller villages and islands can grow or create their own necessary goods. Barter remains an important part of this subsistence economy. In larger communities, cooperative societies dominate commercial life, controlling almost all retail outlets, the marketing of local handicrafts, and the supply of fish to the capital.
