Answer:
Migrants eventually induce social, economic, and political problems in receiving countries, including
1) increases in the population, with adverse effects on existing social institutions;
2) increases in demand for goods and services;
3) displacement of nationals from occupations in the countryside and in the cities;
4) increases in the size of the informal sector of the national economy;
5) deterioration in the salary structures of the informal, rural, and urban sectors of the economy;
6) transculturation;
7) occasional loss of customs and traditions by the local population; and
8) the introduction of diseases and social problems. The receiving countries do benefit from the infusion of skills.
