The author reviews a selection of studies on the behavioral aspects of migration, with emphasis on the process leading up to the decision to migrate. The focus of this review is not on the short-term factors leading to the actual migration decision but on the background factors that lead to the contemplation of migration. The perception by potential migrants of the environment in which they are living as opposed to that of the place to which they might move is considered. (summary in ENG, GER)

Reasons why some women repeatedly resort to abortion are examined. The author suggests that the refusal to practice the alternative of contraception on a regular basis indicates uncertainty over choices in sexual life rather than irrational or pathological behavior. The primary focus of this article is on France. (summary in ENG, GER, SPA)

"This article about the new German law on foreigners which came [into] force on 1-1-91, emphasizes the changes made to the 1965 law and the differences between the situations of foreigners in France and Germany. Two changes of attitude are to be noted: the introduction of a right of residence and of an 'earlier' naturalisation. This naturalisation which is limited to young foreigners and foreigners who have been living in Germany for a long time, finally gets away from the principles of racial...tendencies [i.e.] the belonging to the socio-cultural German Community."

The native and immigrant populations of Switzerland are examined and compared. "The latter represents today 18% of the total population and its age structure tends to draw nearer to that of the Swiss by an aging process. The sex ratio is much different in the two communities. In fact, the foreign population has a strong masculine predominance, especially among the holders of short duration permits. In addition, the diminution in the number of Italians and Spaniards goes with the arrival of the new nationalities (Yugoslavs, Portuguese and Turks) in the labour market and one can observe, as for the Swiss, that the foreign labour, generally speaking, joins more and more the tertiary industries."

"Nowadays 75% of foreigners living in Switzerland have a permanent residence permit. A new phenomenon goes along with this stabilisation: the aging of this resident foreign population, especially Italians and Spaniards who arrived in Switzerland in the fifties and sixties. This trend will have definite consequences on the costs of Swiss social security benefits. Our research project aims at clarifying which factors influence those immigrants who are near retirement to decide whether to stay or go back to their home countries." (SUMMARY IN ENG AND GER)

"Almost half of...over-45s born in French overseas departments and living in mainland France had plans to return overseas by the year 2000. The desire to return is more clear-cut among the 50 to 54 year olds. The younger people have yet to think seriously about retirement, whilst a number of the oldest individuals have already made definite plans." Data are from a survey carried out in 1992.

The authors analyze the geographic implications for France of projected population growth up to the year 2015. "There would be a higher concentration of people in the Mediterranean and Paris area regions, while the Massif Central and the North-East quarter of the country, with the exception of Alsace, would see their populations fall. Migratory movements should help the Paris area to best resist the general aging in France. The fact that the Paris area attracts students and young working people contributes to both its demographic growth and its youthfulness compared with the rest of France. Conversely, the aging of the West will escalate if the arrival of people around retirement age continues." (SUMMARY IN ENG AND GER AND SPA)
