How to arrange relocation to make the most populous community have the least population after relocation?

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, and young people are 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.

Influencing factors (1) Natural environment factors

1. Climate not only directly affects people's health, but also affects the soil, vegetation and hydrology of a region, which has an important impact on human production and life.

2. The distribution and change of fresh water largely determines the spatial pattern of human life and production, thus determining the direction and scale of human migration.

3. Soil is an important condition affecting agricultural production.

4. Minerals are the basis of resource production, especially the development of manufacturing industry.

Socio-economic factors

1, economic factors: the main and often effective factors of population migration. The more the economy develops, the more the migration between regions is restricted by economic conditions.

In most cases, population migration is to pursue better economic income and thus have a better living standard. (2) Macroscopically, the change of economic layout will also cause the migration of a large number of people. For example, the establishment of special economic zones in China attracted a large number of people to move in.

2. The development of transportation and communication has relatively narrowed the distance between regions, reduced all kinds of difficulties that hinder population migration and promoted population migration. In recent centuries, more and more large-scale, large-scale and large-span migrations of human beings have been related to this.

3. The development of culture and education has changed people's attitudes and expectations towards life and the outside world, thus promoting population migration.

4. Marriage and family, marriage is the main factor affecting the migration of young people; Family factors (such as family reunion) play an important role in the migration of minors and the elderly.

(3) Political factors

1, implementation of policies, especially population migration policies.

Reasonable policies can promote the reasonable and normal migration of population; Unreasonable policies, or reasonable policies but unreasonable measures to implement these policies, will have the opposite effect.

2. War destroys the normal living environment and order of human beings, and often causes population migration.

For example, during World War II, the population migration in Europe reached 30 million. At the end of the 20th century, tribal wars in Rwanda and Congo in Africa and conflicts in the Balkans in Europe also caused millions of people to migrate.

3. Political changes, political changes in a country and changes in the political center.
