The present book focuses on the dynamics of internal and international migration at origin. In developing countries, labour migration is poverty-driven and adopted as a household livelihood strategy. It occurs from lagging regions to the prosperous regions in response to regional disparity. In India, labour migration is characterized by illiterate or semi-literate, unskilled or semi-skilled, young able bodied rural youth who move to various urban centres in search of employment. Eastern Uttar Pradesh is one of the highest populated and the most backward regions in India. History of male migration from this region begins in the first quarter of 19th century in the form of Indentured labour to British and French sugarcane plantation colonies. Since then, destinations of migrants have been shifting in response to global economy and industrial development in the country but the intensity of migration remained very high. As the migration is economically motivated, its impact is seen in the form of remittances.Migration not only brings about changes in economic condition but also in socio-cultural and demographic status of the left behind families.
