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 ...

Geographic mobility, population mobility, or more simply mobility is also a statistic that measures migration within a population. Commonly used in demography and human geography, it may also be used to describe the movement of animals between populations. These moves can be as large scale as international migrations or as small as regional ...
A specific mass migration that is seen as especially influential to the course of human cultural and anthropomorphic history may be referred to as a 'great migration'. For example, great migrations include the Indo-European migrations to Europe, the Middle East, and South Asia during the Bronze Age, the Bantu migrations across sub-Saharan Africa, Barbarian invasions during the Roman Empire ...
