True, Refugees fleeing war made up the majority of the world's external migration in the second half of the 20th century.
According to traditional definitions, a refugee is a person who has fled their native country and cannot or will not go back because of a valid fear of persecution. Such a person may be referred to as a "asylum seeker" until the contracting state or the UNHCR, if they formally submit an application for asylum, grants them refugee status. The United Nations Office of the UNHCR is the principal international organization in charge of organizing refugee protection. The majority of Palestinian refugees are supported primarily by the United Nations Relief and Works Agency (UNRWA), which is the organization's second office for refugees.
