There is considerable debate about the effects of today's family structures on support arrangements for older people. Using representative data from The Netherlands, the study reported in this paper investigates which socio-demographic characteristics of adult children and their elderly parents, and which motivations of the adult children, correlate with children giving practical and social support to their parents. The findings indicate that the strongest socio-demographic correlates of a higher likelihood of giving support were: having few siblings, having a widowed parent without a new partner and, for practical support, a short geographical distance between the parent's and child's homes. Single mothers were more likely to receive support than mothers with partners, irrespective of whether their situation followed divorce or widowhood. Widowed fathers also received more support, but only with housework. A good parent-child relationship was the most important motivator for giving support, whereas subscribing to filial obligation norms was a much weaker motivator, especially for social support. Insofar as demographic and cultural changes in family structures predict a lower likelihood of support from children to elderly parents, this applies to practical support, and derives mainly from increased geographical separation distances and from the growing trend for parents to take new partners. Social support is unlikely to be affected by these changes if parents and children maintain good relationships.

Gerontologists have emphasised that older adults are not only recipients of support but also important support providers. Using data from the first wave of the Netherlands Kinship Panel Study of 727 middle-generation adults aged 45 to 79 years, we examined the associations between loneliness and giving support up, across and down family lineages. Overall, the findings were consistent more with an altruism perspective, that giving brings rewards, than with an exchange perspective, which emphasises the costs of giving support. The results showed an inverse relationship between the number of generations supported and loneliness, and that those engaged in balanced exchanges with family members in three generations (parents, siblings and children) were generally the least lonely. As regards the direction of support giving, the findings showed that the association between giving support and loneliness was insignificant if the support was for parents, negative for support to siblings, and positive for support to children. Imbalanced support exchanges were differentially associated with loneliness, and depended on the type of family relationship involved. Non-reciprocated support made parents more vulnerable to loneliness, whereas non-reciprocated giving in sibling ties was associated with low levels of loneliness. Imbalanced support giving in relationships with parents was not associated with loneliness.
