Demographer; Teacher of applied Statistics and Demographic Methods

Sven Drefahl,
Senior Lecturer in Demography

I am a Senior Lecturer in Demography and my research spans a range of interdisciplinary topics at the intersection of Demography, Sociology, Epidemiology, Public Health, and Statistics.

I am currently studying the relationship between migration and mortality, determinants of COVID-19 mortality, and more generally the ageing of the Swedish population. The majority of my research is based on individual-level register data of the total Swedish population. Beyond that I am also interested in international trends of health and mortality and demographic methods.

I am currently teaching demographic methods and statistical methods at the advanced level. Given that I am a Demographer using mainly longitudinal register data I have expert knowledge on most flavors of hazard regression (aka survival analysis, aka event-history analysis). I have also a longstanding interest in demographic micro-simulations.
