Although demography continues to be the most prominient discipline concerned with poopulation dynamics, involvement of other disciplines is highly desirable. The case for a multidisciplinary approach to population theory has been aptly stated by Kurt Mayer: "Any meaningful interpretation of the cause and effects of population changes must... extend beyond formal statistical measurement of the components of change, i. e. fertility, mortality and migration, and draw of the thoeritical framework of several other disciplines for assistance. A theory of epidemiologic transition, sensitive to the formulations of population theorists who have stressed the demographic, biologic, sociologic, economic and psychologic ramifications of transition theory and of the need for comprehensive approaches to population dynamics stimulated the development of this theory.
