Centre for Demographic and Ageing Research (CEDAR) is based at Umeå University. CEDAR strives to support, strengthen and stimulate research on population and ageing. To reach this goal, CEDAR build population databases of the highest possible quality and make these available for researchers. The Centre’s databases are developed and managed by the Demographic Data Base, a unit that has helped Umeå University get a leading position in the area of population history ever since the 1970’s. The research is in turn conducted within CEDAR Research, which gathers Swedish and international researchers from a variety of backgrounds – i.e. history, cultural geography, medicine and statistics.
