Push and pull factors in migration according to Everett S. Lee (1917-2007) are categories that demographers use to analyze human migration from former areas to new host locations. Lee's model divides factors causing migrations into two groups of factors: push and pull.
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.
Studies show that the pre-modern migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about 1.75 million years ago. Homo sapiens appeared to have occupied all of Africa about 150,000 years ago; some members of this species moved out of Africa 70,000 years ago (or, according to more recent studies, as early as 125,000 years ago into Asia, [1] [2 ...

The net migration rate is the difference between the number of immigrants (people coming into an area) and the number of emigrants (people leaving an area) per year divided by the population. [1] When the number of immigrants is larger than the number of emigrants, a positive net migration rate occurs.
The combination of declining rural jobs and a persistently high rural fertility rate has led to rural-urban migration streams. Rural flight also contains a positive feedback loop where previous migrants from rural communities assist new migrants in adjusting to city life. Also known as chain migration, migrant networks lower barriers to rural ...
