They are semi-nomads, alternating residence on the swidden plot, in the forest and along the rivers. Their territory is a valley and its surrounding slopes, about 240 km2. High mobility between the village, their permanent base (about 15 families), camps in the fields and in the forest (only part of the group, sometimes up to half).
It seems that over one year a Batak group spends three months overall in the village, three and a half in forest camps and over five months in dwellings close to their fields. Also, one or two weeks are spent visiting other communities.
* Small-scale swidden agriculture provides the supplementary tubers
and cereals for their diet.
* Hunting is very important.Wild pig (Sus celebensis),
squirrel, peacock, various birds and snakes. But game is beginning to dwindle
because they sell it to farmers in the plains or share the take if the latter
lent them a gun.
* Fishing, together with mollusc and shellfish gathering is done in
rivers and on the coast (which is never very far).
* An important part of their means of subsistence come from contacts with
neighbouring populations : half their food is provided for by their own
activities (hunting, fishing, gathering, and agriculture), the other half is
obtained through wage labour and the sale of forest products.
- Sale of forest products : honey, meat, Agathis resin, rattan.
- Wage labour : they work in the fields for neighbouring ethnic groups (especially the Tagbanua), to help clear the forest or harvest the crops (this includes coffee picking).
* Staple food is provided by hunting and by their own crops : 60% of
carbohydrates (tubers, cereals) are provided by their own crops and by
exchanges, and 10% by gathering activities ; 80% protein come from game, 10%
from fish, but only 5% from domestic animals.

* However, the Batak are in a situation of cultural decline because
they are loosing their specific characteristics through increasing numbers of
mixed marriages and through loss of their economic independence.
