The study ‘Internal Migration in India and the Impact of Uneven Regional Development and Demographic Transition across States: A Study for Evidence-based Policy Recommendations’, supported by the United Nations Population Fund (UNFPA) and published by the Institute for Human Development (IHD), analyses the relationship between the pattern of migration and the pattern of development, looking at both demographic and economic variables. It provides an assessment of the contribution of rural-urban migration to urbanization during 2001-11; a detailed analysis of short-term migration using data from different sources and a review of migration policies from the perspective of states. Since the onset of COVID-19, the issue of labour migration in India has assumed centre-stage. The study can readily feed into an understanding of migration and policy responses urgently required in the COVID-19 pandemic and post-pandemic period.
