[Unpublished] 1983 Mar 9. Presented at the International Conference on Population, 1984, Expert Group on Population Distribution, Migration and Development, Hammamet, Tunisia, 21-25 March 1983. Items 4 and 8 of the provisional agenda. 80 p.This paper assesses 4 aspects of international migration during the 1970s: permanent settler migration, migration of labor, illegal or undocumented migration, and refugees. In the last decade, the flow of permanent settlers has declined in most of the main receiving countries. Only in the US has the intake of permanent settlers steadily increased. European immigration has declined in relative importance, while that originating in Asia (except for Israel) has gained. Labor migration has decreased in Western Europe, South Africa, and the US. In contrast, the Middle East has continued to receive substantial numbers of foreign workers. The most important increases have occurred among workers from non-Arab Asia supplied through turn-key projects. Although illegal/undocumented migration is considered to account for a sizable proportion of international flows, the lack of accurate data makes it impossible to ascertain whether this practice is increasing, remaining stable, or even declining. The US, Venezuela, Hong Kong, Italy, and Nigeria experienced particularly high levels of illegal immigration during the past decade. Finally, there is evidence that refugee movements are growing in size and diversity. Most refugee flows originate and end in the developing regions. It is urged that mechanisms to promote and aid either the resettlement of refugees in 1st asylum countries or their voluntary repatriation be strengthened.
