"Since the 1948 Arab–Israeli War, Palestinians have experienced several waves of exile and have spread into different host countries around the world.[5] In addition to the more than 700,000 Palestinian refugees of 1948, hundreds of thousands were also displaced in the 1967 Six-Day War. In fact, after 1967, a number of young Palestinian men were encouraged to migrate to South America.[6] Together, these 1948 and 1967 refugees make up the majority of the Palestinian diaspora.[5][7] Besides those displaced by war, others have emigrated overseas for various reasons such as work opportunity, education[8][9] and religious persecution.[7] In the decade following the 1967 war, for example, an average of 21,000 Palestinians per year were forced out of Israeli-controlled areas.[10] The pattern of Palestinian flight continued during the 1970s, 1980s, and 1990s.2
