The basic social unit of the Tirol is the neighborhood, consisting of four to six neighboring farm households. Cooperative tasks are organized within this group under the leadership of the several household heads, who share ties of friendship and trust through long association with one another. The hierarchical relations that characterize the farm household, with the owner-heir at the head, have implications beyond simple household and interhousehold activities as well. Those who serve as head of household also tend to monopolize political activity in the village, hold village-council office, and dominate the decision-making processes regarding Village concerns. Tirol communities enjoy self-government; each one has its own mayor, elected community council, and regulatory committees.
