The I-wak live in small fenced-in barrios within the larger communities of ethnic groups such as the Ibaloy; the fences, along with pig sties, are generally integrated into the housing architecture. Kin-based communities are organized on a religious basis around a common ritual house which promotes the sharing of meat. A personal prestige feast called padit is celebrated at least once by each adult male, for which he must raise a large herd of pigs the meat of which will be distributed to members of the community over a period of several days.
