Human migration is physical movement by humans from one area to another, sometimes over long distances or in large groups. The movement of populations in modern times has continued under the form of both voluntary migration within one's region, country, or beyond and involuntary migration (which includes the slave trade, trafficking in human beings and ethnic cleansing). People who migrate are called migrants or, more specifically, emigrants, immigrants, or settlers, depending on historical setting, circumstances and perspective. Humans sometimes migrate on a daily basis, in which case it is commuting and the humans are called commuters. There are also tourists, who temporarily travel to go on vacation, and pilgrims, who do so for religious reasons. The rest of this article will cover migration in the sense of a "change of residence", rather than the temporary migrations of travel, tourism, pilgrimages, or the commute.
