Three conditions of population migration

Three conditions, one is spatial displacement, which is generally defined by administrative divisions. The second is the change of residence. The third is the time limit, generally more than one year. Population migration generally refers to the spatial flow of population between two regions, which usually involves the permanent or long-term change of population residence from the place of emigration to the place of emigration.

The main factor of population migration is 1. Economic factors: better living conditions, more employment opportunities and higher income.

2. Political factors: political persecution, war and marginalization.

3. Socio-cultural factors: religion, nationality.

4. Eco-environmental factors: catastrophe (day/person).

Economic reasons are the main reasons for 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, and young people are more than children and the elderly.

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.
