This volume, an analysis of international trends in student exchange programs, is presented in two parts. Part One contains the actual analysis, supplemented by an annex of tables which summarize world and regional trends. Part Two contains "country tables" for 151 countries and territories in which students abroad are presented according to (a) their country of study and (b) their field of study. This is the first comprehensive study on this subject published by UNESCO. The study analyzes statistical data on foreign students which have been collected by the Office of Statistics of Education. This study serves as a reference source for those interested in international exchanges and, more specifically, as a documentation for national authorities concerned with manpower planning. A summary of major findings and the computer-printout data on which the study is based are included. The text is presented in French and in English. (Author/RL)
