Like the rest of Samoa, Savaii is made up of villages with most of the land collectively owned by families or "ʻaiga". Most people on Savaii, 93% of the island population, live on customary land. The heads of the family are called "matai", the holders of family names and titles. An extended family can have a number of chiefs with different chief titles. Men and women in Samoa have equal rights to chief titles which are bestowed by consensus of the extended family. Traditionally, male and female roles are defined by labours and tasks, chiefly status and age. Women play an important role contributing to family decisions as well as village governance. Elders are revered and respected. Social relationships are dictated by cultural etiquettes of politeness and common greetings.
