Organisation Profile

The Population Research Unit (PRU) is a section in the Faculty of Social Sciences, University of Helsinki in Finland.

The research of the unit covers a wide range of topics from the analyses of mortality, health and ageing to family demography, social mobility and social exclusion. In addition to studies focusing on the Finnish society many studies are conducted in international collaboration with colleagues from other European countries, East-Asia and the United States. The Population Research Unit focuses on quantitative research and uses extensively Finnish longitudinal register data as well as survey questionnaires, clinical data and their different combinations from various countries.

The unit collaborates with doctoral seminar Population, Health and Living Conditions (a sub-programme of the Doctoral Programme in Social Sciences) that focuses on advanced quantitative social research. The unit forms an integral part of the cross-disciplinary Centre for Population, Health and Society that received the highest recognition in the latest research and doctoral training assessment exercise at the University of Helsinki. The head of the Population Research Unit is Pekka Martikainen, Professor of Demography.
