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. He ...
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).
Zelinsky's Theory of First Effective Settlement was that the dominant culture of a nation is defined by the first settlers who came to an area who are able to effect a self-perpetuating society. The theory states that these first settlers have significant impact on the social and cultural geography of the area, however few these first settlers ...
He established a theory of human migration in the 1880s that still forms the basis for modern migration theory. The following was a standard list after Ravenstein's (1834–1913) proposal in the 1880s. The theories are as follows: Every migration flow generates a return or counter-migration. The majority of migrants move a short distance.
Stouffer theorises that the amount of migration over a given distance is directly proportional to the number of opportunities at the place of destination, and inversely proportional to the number of opportunities between the place of departure and the place of destination. These intervening opportunities may persuade a migrant to settle in a ...
The subsequent preference for minimizing distance and its cost underlies a vast array of geographic patterns from economic agglomeration to wildlife migration, as well as many of the theories and techniques of spatial analysis, such as Tobler's first law of geography, network routing, and cost distance analysis. To a large degree, friction of ...
Geographic mobility is the measure of how populations and goods move over time. Geographic mobility, population mobility , or more simply mobility is also a statistic that measures migration within a population.
Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. [1] The distance decay effect states that the interaction between two locales declines as the distance between them increases.
