[Multidimensional mathematical demography: a survey]

The development of multidimensional mathematical demography and its application to the analysis of such changes in life status as marriage, occupation, and migration is discussed. "This article presents an overview of the methods and models specific to this new branch. It stresses (1) their relationship with the methods and models of classical mathematical demography, (2) their field of application, (3) their elaboration, and (4) a few methodological and empirical questions raised by their use."
