For the Population Study, a panel of elders is taken from 10 different age cohorts, beginning at the age of 60 up to 96 years with a 6-year interval between the younger cohorts (up to 78 years) and a 3-year intervals thereafter. New cohorts of 60- and 81-year olds joined the study in 2007-2010, and 2014-2016, respectively. The Care System Study is a systematic, longitudinal, individually-based collection of data of all persons 65+ years living in the area with their registration connected to assistance decisions.
