impact of Migration in the distribution of population

The shifting of the settlement of individuals or group of people from one geographical unit to another or fromone place to another is called migration. It is a main factor like birth and death to bring changes in population. It decreases the population of the place of origin and increases the population of the place of destination. people migrate from one place to another for better falities, security and comfortable life. It is a continuous process. However , Migration is not a biological phenomenon like birth and death. It is usually guided by the desire and attitude of the people of origin and place of destination. It decreases the population of a place of origin which is not good. however due to migration the natural enviroment of a place of origin remains safe from over exploitation and degradation. for the past few years , people have been migrating from the Himalayan regions to the tarai , which has resulted the decrease in the population of Himalayan region.
