Since H. Otley Beyer first proposed his wave migration theory, numerous scholars have approached the question of how, when and why humans first came to the Philippines. The current scientific consensus favors the "Out of Taiwan" model, which broadly match linguistic, genetic, archaeological, and cultural evidence.
Beyer's theory showed the first wave as the negritos (25,000–30,000 YBP), the second wave as the Indonesians (5,000–6,000 YBP), and the third wave as the Malayas (2,500 YBP). Beyer conducted archaeological surveys in Luzon, Palawan, and the Visayan Islands and suggested that terraces were constructed as early as 2000 years ago. [2]
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).
Henry Otley Beyer (July 13, 1883 – December 31, 1966) was an American anthropologist, who spent most of his adult life in the Philippines teaching Philippine indigenous culture. A.V.H. Hartendorp called Beyer the "Dean of Philippine ethnology, archaeology, and prehistory".
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.
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.
The subject is equally contentious among academics who have espoused numerous theories for the effects of immigration, both illegal and legal, on foreign and domestic economies. Traditional international economic theory maintains that reducing barriers to labor mobility results in the equalization of wages across countries. [1]
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 ...
