The extent of Dangu territory could not be established by Tindale, who located them in the general area of Yirrkala Mission, Cape Arnhem, Melville Bay, and Port Bradshaw.
Like all Yolgnu societies, the Dangu, identified as a grouping of clans (mala) sharing similar dialects, were organized according to the Dhuwa and Yirritja moieties. Their ethnonymic identity as a unified group was based on their common word for the demonstrative pronoun "this." They are divided into six clans according to which moiety they belong to, 4 Dua, and 6 Yirritja. The Dua moiety:
- 1. Galpu (Gälpu, Galbu, Kalpu).
- 2. Golumala.
- 3. Ngajimil. (Ngayimil, Ngeimil, Makkanaimulmi).
- 4. Riratjingu. (Rirratjingu, Rirraljinga, Riraidjango, Wurrulul, Woralul, Urorlurl).
The Jiritja moiety:
- Yirgala. (A toponym).
