Demography is an interdisciplinary science that focuses on the study of the population, its size, composition and change.
Populations change over time through the interaction of three central demographic processes: fertility, mortality and migration. In demographic research, this focus is expanded to include processes related to family dynamics, health and integration. Demography is a quantitative science in which advanced statistical methods are used to analyze large data sources, often register data. In addition, the subject of demography at Stockholm University often has a sociological focus, in the sense that our research focuses on the relationship between population processes and various social, economic, cultural and political factors.
