This paper introduces the Special Issue of four empirical studies on the provision of family support to older people that have been written members of the Family Support for Older People: Determinants and Consequences (FAMSUP) network. They have in common the use of individual-level data and recognition of the importance of demographic forces, cultural variations and public policy in shaping patterns of elder care. The four papers are also explicitly comparative, and emphasise both between- and within-country differences.
