The term may refer to non-human entities, such as converting a foreign currency into the currency of one's own country, as well as the return military personnel to their place of origin following a war.
Global workforceGlobal workforce refers to the international labor pool of workers, including those employed by multinational companies and connected through a global system of networking and production, foreign workers, transient migrant workers, remote workers, those in export-oriented employment, contingent workforce or other precarious work.

Pre-modern human migrationThis article focusses on prehistorical migration since the Neolithic period until AD 1800. See Early human migrations for migration prior to the Neolithic, History of human migration for modern history, and human migration for contemporary migration. Paleolithic migration prior to end of the Last Glacial Maximum spread anatomically modern humans throughout Afro-Eurasia and to the Americas. During the Holocene climatic optimum, formerly isolated populations began to move and merge, giving rise to the pre-modern distribution of the world's major language families.
