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 ...
By the end of the Second Great Migration, African Americans had become a highly urbanized population. More than 80% lived in cities, a greater proportion than among the rest of American society. 53% remained in the Southern United States, while 40% lived in the Northeast and North Central states and 7% in the West.
By the late 1970s, as deindustrialization and the Rust Belt crisis took hold, the Great Migration came to an end. But, in a reflection of changing economics, as well as the end of Jim Crow laws in the 1960s and improving race relations in the South, in the 1980s and early 1990s, more Black Americans were heading South than leaving that region.
Early modern human expansion in sub-Saharan Africa appears to have contributed to the end of late Acheulean industries at about 130,000 years ago, although very late coexistence of archaic and early modern humans, until as late as 12,000 years ago, has been argued for West Africa in particular.
Young people between the ages of 15 and 30 were predominant among newcomers. In this wave of migration, constituting the third episode in the history of U.S. immigration, nearly 25 million Europeans made the long trip. Italians, Greeks, Hungarians, Poles, and other Slavs made up the bulk of this migration, with 2.5 to 4 million Jews being among ...
The Migration Period (c. 300 to 600 AD), also known as the Barbarian Invasions, was a period in European history marked by large-scale migrations that saw the fall of the Western Roman Empire and subsequent settlement of its former territories by various tribes, and the establishment of the post-Roman kingdoms.

New York’s surging migrant growth has seen the state’s population tick up between 2023 and 2024, reversing a years-long trend as locals leave the state for cheaper living or warmer weather.
The coastal migration models provide a different perspective on migration to the New World, but they are not without their own problems: One such problem is that global sea levels have risen over 120 metres (390 ft) [140] since the end of the last glacial period, and this has submerged the ancient coastlines that maritime people would have ...
