Economic reasons are the main reasons in population migration, such as getting rid of poverty and unemployment, improving life, or getting rich and seeking career success. In addition, politics, religion, culture, war and famine may also lead to immigration. The direct consequences of population migration are manifested in the different influences on the population, gender and age composition of the emigration place and the immigration place.

Generally speaking, there are more men than women among immigrants, and young people immigrate more than children and the elderly. From the indirect economic and social consequences, the population pressure in the emigration area is reduced, and remittance income may be obtained, but the labor force is reduced, especially the skilled and highly educated labor force moves out, which makes the expenses of raising and education in the emigration area suffer huge losses. For immigrant areas, the increase in population and labor force is economically beneficial, but it may also bring ethnic conflicts or other social problems.

Political factors have a special influence on population migration. Among them, policy, political changes and war are important influencing factors. A country's policies, especially those related to population migration, will have an important impact on population migration. Reasonable policies can promote the reasonable and normal migration of population; But if the policy is unreasonable, or the measures to implement it are unreasonable, it may have the opposite effect.

War destroys the normal living environment of human beings and often leads to population migration. For example, during the Second World War, the population migration caused by war in Europe reached 30 million. Tribal wars in Africa, Rwanda and Congo at the end of the 20th century caused millions of people to migrate.
