Migration between core and peripheral regions: a description and tentative explanation of the patterns in 22...

"In the developed world at least, the century-long migration towards the high density core regions is over. To establish this thesis, internal migration statistics for 22 countries are examined, covering the period 1950-1979. Of these 22 countries, five categories are distinguished: (1) the countries of north-western Europe...; (2) the countries of North America...; (3) countries on the periphery of western Europe...[and] Japan and New Zealand; (4) the countries of eastern Europe...; and (5) two advanced developing countries in eastern Asia...." Migration trends among countries in the five categories are described, and a tentative explanation of these patterns is offered. "[An] appendix contains the data from which the figures in the text have been constructed, the exact sources from which the data have been taken, and the constituent administrative subdivisions of the regions chosen for study."
