Overview of population mobility

population shift

Population migration does not belong to population migration, but it is more common and frequent than population migration, and floating population cannot be called immigration. Population mobility is divided into periodic mobility and round-trip mobility.

In population statistics, the phenomenon that the registered place of population is inconsistent with the current place of residence and has been away from the registered place of population for more than half a year is collectively called "separation of people and households". "Household separation" can be divided into inter-provincial household separation and inter-regional (county), street and township (town) household separation within a province (city) according to whether the separated space spans the provincial cities. Among them, the former is called inter-provincial floating population, which is a long-distance flow across provincial boundaries, and the latter is called floating population within provinces (cities).

Definition: Due to the role of the household registration system under the planned system, the traditional population migration in China refers to the permanent change of the household registration location. In fact, there are a lot of non-permanent changes in non-household registration or residence, which is commonly called mobility.
