Increasing pressure on agricultural land, climate change, poverty and low level of social and economic development has been pushing the poor and unskilled in rural areas to urban areas. While migration is conventionally attributed to economic distress and shocks it is increasingly becoming an accumulative option for poor and non-poor alike. The purpose of the study is to address the void in research in migration in the emerging economic context and contribute to urban restructuring and migration policy. The study is undertaken in four urban areas; two megacities New Delhi and Bangalore.
