Question

Answer in detail:

 Examine the impact of migration on the population structure of a country.

Answer 1

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