ABSTRACT
Time and space are two integral parts of the measurement of any process. Until recently, much greater attention has been paid to the time dimension in the study of demographic transition (such as a staged process of the changes in population reproduction registered at the level of fundamental shifts of the mean values of demographic characteristics). Beginning with the works by Landry and Notestein in the 1930s, this staged concept of demographic dynamics has become a stable research tradition based upon solid and continuously expanding empirical knowledge.
