Migration is the permanent or semi-permanent change of residence of an individual or group of people over a significant distance – the movement of people from one place to another. Urbanisation is the process in which there is an increase in the proportion of population living in towns and cities. "Human Migration" is one of the most important aspects of social science and one of the most important dynamic human activities from the very beginning of human life.
1. Meaning of Migration
United Nations Organization definition: Migration is a form of geographical mobility of population between one geographical unit and another, generally involving a permanent change of residence.
- In the early days, people moved from one place to another in search of food.
- When people stopped living in forests and adopted civilised life, they developed relationships with domesticated animals and fertile land, almost left nomadic life and lived in permanent settlements.
- They then moved from region to region in search of fertile land for cultivation.
