European migrations to the Americas and Australia have often been noted as an important part of world history, but movements to the frontiers, factories, and cities of Asia and Africa have largely been overlooked. This paper will show that migrations to northern and southeastern Asia were comparable in size and demographic impact to the transatlantic flows and followed similar cycles of growth and contraction. These migrations were all part of an expanding world economy, and a global perspective suggests ways in which that economy extended beyond direct European intervention. A global perspective also compels us to extend the traditional ending point for the era of mass migration from 1914 to 1930, and to be more aware of how political intervention has shaped the world into different migration systems and led scholars to wrongly assume that these systems reflect categorically different kinds of migration.
