Population Analysis for Policies & Programmes 

This course introduces users to the methods used by demographers to analyse population data, and the sources of this data and the methods used to collect this data. Throughout the course, students are introduced to the types of issues of interest to demographers through real examples. Included are sessions that introduce broad areas of research through discussion of both global and national trends and sessions that show how demographic methods may be used in researching a range of areas, such as reproductive health, morbidity and health profiles, and the effects of ageing on a population.
