The research group on “Population ageing” is located at the Faculty of Social Sciences at Helsinki University. It is led by Kathrin Komp-Leukkunen, associate professor in social policy. The members of this working group study a range of topics related to old age and population ageing, often in a country-comparative perspective. Example topics are life-course structures, policy reforms in reaction to population ageing, older workers and retirees, population ageing and sustainability, older individuals during the COVID19-pandemic, and simulations of the future development of population ageing. This homepage introduces the members of the research group and some of their research.
