Profilbild Sven DrefahlHi and welcome to my personal website. I am a researcher at the Demography Unit of Stockholm University and the Department of Environmental Medicine at Karolinska Institute. Most of my research deals with trends and determinants of mortality and population aging. I also teach classes at the graduate level, mainly on basic and advanced demographic methods. Before joining Swedish Academia in 2010 I have been a doctoral student at the Max Planck Institute for Demographic Research in Rostock, Germany.


On this website, you can find more about my research and teaching. I also like to make fancy graphs and animations in R as often as possible, so I hope to put some of them online pretty soon.



Most of my research deals with health and mortality in human populations from a demographic perspective. Some of my topics are closely linked to the social sciences, particularly sociology, others are rooted in epidemiology. An overview on my research you can find here.


Demography often has a comprehensive view on populations. The animated figure below gives an example and reflects the dramatic shifts in mortality in the 20th century for the Swedish case. The figure shows which age groups have contributed to the increase in life expectancy. At the beginning of the 20th century almost all progress was made at the young ages, meaning that life expectancy increased because the survival conditions at ages below 14 and especially for infants became much better. Recently, the majority of progress in life expectancy is due to reductions in mortality at old and very old ages. The figure requires an HTML5 capable browser.


This website contains an overview of my work and interests, however, a .pdf version of my CV can be downloaded as well.
