The Hadza are organized into bands, called 'camps' in the literature, of typically 20–30 people, though camps of over a hundred may form during berry season. There is no tribal or other governing hierarchy, and conflict may be resolved by one of the parties voluntarily moving to another camp. The Hadza live in a communal setting and engage in cooperative child rearing, where many individuals (both related and unrelated) provide high quality care for children.
