This course is designed for learners with prior exposure to the field of demography as well as those interfacing with the field for their first time. The course begins with a brief history about the field of Demography. To appreciate the applicability of course content in everyday life, learners will gain insights into how Demography is linked to the different sectors in National economies, with particular emphasis on how skills acquired through the course can be relevant in any given sector. Learners will gain an understanding of the major sources of data for demographic analysis and some of the common indicators, as used in measuring population change, to which these data can be relevant. The course also focuses on population size and structure and how the components of change (fertility, mortality and migration) work to alter the structure, eventually leading to population change. The course explores major demographic theories and how these can be exploited to account for current demographic changes. The course will conclude by examining the current global population trends, helping learners make meaning of the different trends.
