M.S.A. Rao points out in the Indian context that although both village and town formed part of the same civilization characterized by institution of kinship and caste system in pre-British India, there were certain specific institutional forms and organizational ways distinguishing social and cultural life in towns form that in village.
Thus, according to Rao, Rural Urban continuum makes more sense.
