"brain drain" is, therefore, generally intended to mean in this study 

 the loss of an educated elite that is required to satisfy the needs for 

 national development, particularly in the long-run.. Beyond this, 

 use of the term is a matter of convenient identification of a subject 

 already widely known under that label. In describing the conditions 

 of bram drain, the study attempts to provide a reasonable statistical 

 basis on migration flows and patterns for analyzing the problem and 

 where possible to support generalizations with specific cases. By ne- 

 cessity, certain assumptions have been made. Also by necessity the 

 study relies upon what are at best impressionistic views derived from 

 the many sources examined. Finally, international development is a 

 v-ast and variegated subject embracing a wide range of problems and 

 issues. This study, while acknowledging this diversity, examines the 

 problem principally from the perspective of brain drain and the pri- 

 mary role of trained manpower in development.
