Originally published in 1979. This volume brings together the work of distinguished demographers, geographers, statisticians and policy-makers who look in detail at various mechanisms by which regional population structures develop. The introduction deals with a synthesis of the area covered in the book and this is followed by the four major sections of population history, fertility, migration and population projections. The book provides the reader with a comprehensive and unique picture of regional populations and demographic development viewed from a variety of temporal and methodological perspectives, and will be of considerable value to all those connected with population studies and regional studies.
