​

Answer 1

Answer:

Migration affect the population of the two particular areas.It increases the population of the place (new place), where people migrate in search of good facilities and decreases the population of the area where people migrate from. It is an unnatural cause that changes the population.

Some studies have shown increased fertility levels in migrants, so the effect of migration on population structure is to deplete the population emigrated from in the young adult groups, to augment this group in the immigrated-to population, and to increase the fertility/birthrate in the new population.
