The movement of people from one place to another place is known as Migration.

Causes of Migration : Migration is caused by a variety of factors including economic, social and political factors. 

Some of them are briefly discussed below.

• Marriage: Every girl has to migrate to her husband’s place after marriage, thus the entire female population of India has to migrate over short or long distance. 
• Employment : The agricultural base of rural areas does not provide employment to all the people living here. In contrast,urban areas provide vast scope for employment in industries, trade, transport & services. Hence people like to migrate towards the urban areas.
• Education : Educational facilities are very low in the rural areas especially those of higher education and rural people have to migrate to the urban centers for this purpose. 
• Lack of security: Large number of people have migrated out of Jammu and Kashmir and Assam during the last few cars due to disturbed conditions there. In this situation, people would like to migrate towards well secure areas.
