5. 5. Kingsley Davis has estimated that for the 55 years from the beginning of World War I to 1968 refugee movements in the European orbit of the Western world totalled 29 million. (If one adds those of Asia, Africa and the Western Hemisphere, the grand total for the world comes to 72 million.) For a detailed description of post-World War II refugee movements, see ILO, International Migration, 1945-1957 (Geneva, 1959).
