Examine the impact of migration on the population structure of a count

1.	Examine the impact of migration on the population structure of a country.
Answer» In migration people move from one place to another place for different reasons. The place from where people migrate outside is called donor region. The place where people migrate to is called recipient region, Due to migration of people there are changes in age structure and sex ratio in both the regions. In donor region due to migration of young male population there is disturbance in the age structure. More females remain in donor area. So, donor area has high sex ratio. In India there is high sex ratio in rural areas due to migration of people from rural to urban areas. In donor region there are changes in age structure as well. More old age people and children remain in donor region which is nonworking/ non-productive population. There is shortage of working population. In recipient region male population increases due to migration of male into region. As a result, sex ratio in recipient region goes down. In many big cities of India sex ratio is less than 85% or 90%. In recipient region the percentage of working population increases. There is more working population than non-working population, which helps in economic development of the region.
