The Zelinsky Model of Migration Transition, [1] also known as the Migration Transition Model or Zelinsky's Migration Transition Model, claims that the type of migration that occurs within a country depends on its development level and its society type. It connects migration to the stages within the Demographic Transition Model (DTM).
While an increase in geographic mobility increases overall economic efficiency, the increased competition for jobs on the local level in otherwise prosperous regions could lead to higher unemployment than before the migration. [4] Female labor supply rates actually have larger statistical effect on mobility than male rates. [7]
Population momentum is a consequence of the demographic transition.Population momentum explains why a population will continue to grow even if the fertility rate declines or continues to decline even if the fertility rate grows.
Human migration is the movement of people from one place to another, [1] with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is the dominant form of human migration globally.
The gravity model of migration is a model in urban geography derived from Newton's law of gravity, and used to predict the degree of migration interaction between two places. [1] In 1941, astrophysicist John Q. Stewart [ 2 ] applied Newton's law to the social sciences, establishing a theoretical foundation for the field of social physics.
Arctic Alaska is also an example of a rural and remote location in the United States where migrants move in and out of. [9] Berman, Huskey and Howe discovered that step migration occurred both upward and downward in an urban and rural hierarchy. [4] Step migration is hierarchical in Alaska as people move from rural villages to regional centres. [9]
In demography, replacement migration is a theory of migration needed for a region to achieve a particular objective (demographic, economic or social). [1] Generally, studies using this concept have as an objective to avoid the decline of total population and the decline of the working-age population.
Circular migration or repeat migration is the temporary and usually repetitive movement of a migrant worker between home and host areas, typically for the purpose of employment. It represents an established pattern of population mobility , whether cross-country or rural-urban.
