Contribution of the demographic factor to the migration turnarounds in Japan,Sweden and Canada

"It is well known that similar changes of migration pattern occurred during recent decades in most developed countries; core regions recorded a greatly decreased net in-migration in the 1970s, but increased net in-migration in the 1980s. Based on shift-share analysis of the migration data of Japan, Sweden and Canada, this paper reveals that changing cohort size, especially related to the fertility fluctuation of baby boom and bust, has played an important role in the turnarounds. Furthermore, it is elucidated from a series of correlation analyses that this demographic factor was closely linked with labour-market restructuring in terms of industrial/occupational employment changes."
