Second, the census.

Population census refers to a one-time survey and registration of the national population within the time specified by the state, in accordance with unified methods, unified items, unified questionnaires and unified standard time points, generally on a household-by-household basis. The census work includes the whole process of census data collection, data collection, data evaluation, analysis and research, editing and publishing. It is one of the most basic scientific methods to collect population data widely used in the world today, and it is the main source to provide basic population data for the whole country.

Third, the reasons for population migration.

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, due to the increase of population and labor force, it is economically beneficial, but it may also bring other social problems. Political factors have a special influence on population migration.
