Abstract- Mobility has been an inherent part of human existence since the day of civilization. Migration in today’s world is shaped by a number of factors related to economic, political, religious, life risk, and various ethnic and sociocultural issues. In this paper, an attempt has been made to investigate firstly, the impact of a variety of economic and noneconomic factors on net in migration and secondly, the impact of net migration on the level of economic development in fifteen major states of india. Using poled cross section data for fifteen major states, it has been found that net migration is positively influenced by level of per capita income and level of road infrastructure, and negatively influenced by unemployment rate and cost of living. The other variable, crime rate, has been found insignifincant as a determinant of migration, indicating that people migrating from on state to other do not concern about risk of life, they are rather concerned abouth basis needs of life. further, migration development relationship tested in the present study indicates that level of development is positively associated with net migration. This finding defends the controversial belief that migration is beneficial for development and there is no reason to raise voice against human mobility in the context of Indian economy.
