In India, urban population always remain concentrated in certain growth centers , among which Mumbai, Delhi and Kolkata are the most important ones. These possess the top three ranks in terms of urban population size. The present paper examines the role of in-migration to the above mentioned megacities. A comparative analysis has been made among these megacities keeping in mind the reasons and source regions of migration. For a proper understanding necessary graphs have been produced, based on census data. From the study it is found that, Kolkata is lagging behind in comparison to Mumbai and Delhi, regarding urbanisation and urban migration related issues. Apart from that, these megacities are creating a polarization effect in terms of population size and infrastructural development compared to their source regions of in-migration.
