In the framework of demographic processes different approaches can be identified. According to their aims these approaches can be differentiated in extrapolative and structural methods. The first ones focus on the homogeneity of trends in order to obtain projection. The second ones are based on structural models relating demographic variables to other kind of variables (geographical, social, economical, etc.).

Abstract
In the framework of demographic processes different approaches can be identified. According to their aims these approaches can be differentiated in extrapolative and structural methods. The first ones focus on the homogeneity of trends in order to obtain projection. The second ones are based on structural models relating demographic variables to other kind of variables (geographical, social, economical, etc.). Nowadays, this distinction is not so clear and the joint use of explorative and explanatory approaches is increasing. In this paper, we focus on the extrapolative features of the Lee Carter model (1992) and propose a reading of such method in the framework of the Multidimensional Data Analysis. Our aim is to propose a data analysis strategy exploiting the analytical and geometrical properties of the Lee Carter method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
