In the villages, families typically occupy mudbrick houses, or compounds with mudbrick or stone walled houses. Villages typically have a headman (''malik''), a master for water distribution (''mirab'') and a religious teacher (''mullah''). Men would typically work on the fields, joined by women during harvest. About 15% of the population are nomadic, locally called ''kochis''. When nomads pass villages they often buy supplies such as tea, wheat and kerosene from the villagers; villagers buy wool and milk from the nomads.
