What is migration and what are its causes?

Migration is defined as movement from one country, place or locality to another in search of better opportunities to settle.When people move from one place to another, the place they move from is called the Place of Origin and the place they move to is called the Place of Destination. 

People migrate for a better economic and social life. There are two sets of causes or factors that influence migration.

• Push factors make the place of origin seem less attractive for reasons like unemployment, poor living conditions, political turmoil, unpleasant climate, natural disasters, epidemics and socio-economic backwardness. 
• Pull factors make the place of destination seem more attractive than the place of origin for reasons like better job opportunities and living conditions, peace and stability, security of life and property and pleasant climate.
