Answer:
Migration is affected by various factors like age, sex, marital status, education, occupation, employment etc. Age and sex are main demographic factors that affect the migration.
Step-by-step explanation:
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. Governments must also do everything possible to facilitate integration of refugees.
