This book represents a multi-disciplinary attempt to analyze and understand the problems relating to migration, both internal and international. Migration is assuming extremely critical significance in contemporary times in the context of rapid industrialization and economic develop­ment. Its significance expands well beyond regional geography, urban planning and housing policies, etc., into problems of law and order, conduct of national integration and management of human relations. Not only demographers and urban specialists, but other social scientists are now finding migration to be an area of absorbing and sustained academic interest. This book brings together twelve essays focussing on the historical, demographic and sociological dimensions of migration. A wide range of migration situations from the rural – rural to international are explored and many conceptual, theoretical and empirical aspects of the phe­nomenon are explored. The principal focus of analysis throughout is on human aspects of migration – poverty, deprivation and subsistence. The book constitutes by its multi-disciplinary perspective a pioneering contri­bution to the sociology of migration and will be useful for social scientists as well as administrators, politicians and social workers.
