The core argument of this article is that the potential benefits of internal migration are not being fully realised because of an inadequate understanding of migration patterns (especially temporary and circular migration), continuing policy barriers to population movement, urban middle-class attitudes, social exclusion on the basis of ethnicity, caste, tribe and gender and poor enforcement of legislation meant to protect the rights of the poor.
