The social institution of caste and the many ways it can create exclusion amongst different groups has a generated much literature in South Asia, primarily focused on India. Caste is often incorrectly characterized as a social hierarchy inherent within Hinduism. In fact, caste is a social phenomenon that exists across groups in South Asia, including Hindus, Muslims, Sikhs and Christians throughout South Asia in varying degrees.
In Pakistan, research and debate on the implications of caste and poverty has been limited. While a substantial literature exists about the social structures of Pakistan, including various caste, kinship groups and tribes such as zaat (caste), biraderi/qaum (kinship groups) and qabila (tribe), development practitioners and policy makers have largely ignored the issue of caste and social exclusion in Pakistan with its links to inequality in rights, access services and representation.
