Annotation	The Berlin Aging Study (BASE) is a comprehensive and in-depth study of a locally representative and heterogeneous sample of 516 older adults, age range 70-105 years, with equal numbers of male and female participants. This article outlines the design of BASE, describes the cross-sectional sample, and reports sample selectivity analyses on 25 criterion variables in which the Pearson-Lawley selection formulae were used. Although the BASE sample is positively biased, it is not restricted in heterogeneity and does not exhibit major differences in patterns of co-variation among variables. This finding supports the use of BASE data for the intended systemic-holistic analyses.
