Berlin Aging Study II (BASE-II)
BASE-II is an extension and expansion of the longitudinal Berlin Aging Study (BASE) and follows 2,200 Berlin residents into older age. The participants form two groups:1,600 participants belong to the older sample, aged between 60 and 80, and 600 participants are between 20 and 35. The younger sample functions as a reference group for the group of older participants. By design, each age subgroup contains equal numbers of males and females.
