Objectives. To investigate whether number of children and, among parents, having a daughter is associated with older people’s likelihood of at least weekly face-to-face social contact and later receipt of help if needed. Method. Multivariate analysis of data from Waves 1 and 2 of the English Longitudinal Study of Ageing (ELSA). Results. Older parents in England had higher chances of at least weekly face-to-face social contact than their childless counterparts but larger family size had only a slight additional effect. For parents, having at least one daughter was more important than number of children. Larger family size was positively associated with receipt of help from a child by parents with activities of daily living (ADL) or instrumental activities of daily living (IADL) limitations. Childless women were more likely than mothers to receive help from friends but even so had lower odds of receiving help from any informal source. Contact with a child in 2002 predicted receipt of help 2 years later. Discussion. These results show some advantages for older parents compared with childless individuals in terms of social contact and receipt of help and, among parents, an additional effect of having a daughter. Changes in family size distributions have implications for the support of older people and for planners of formal services. n the U.K., as in many other populations, there were a number of significant changes in the family-building patterns of cohorts born in the 20th century. These included a trend toward increased concentration on family sizes of two children and a decline in the proportions of women having larger families of four or more children. The proportions never having children showed a U-shaped trend, first falling and then rising, with women born in the mid-century including the lowest proportions remaining childless (Chamberlain & Smallwood, 2004; Murphy, Martikainen, & Pennec, 2006). Reductions in mortality also mean that the propor tions of children surviving to their parents’ later life have increased substantially, although now that survival to midlife is almost universal, the potential impact of future changes in mortality is much lower (Murphy & Grundy, 2003). Many previous studies of the implications of family size for the social support and well-being of older people have focused on comparisons between the childless and those with children. Past and possible future changes in family size distributions suggest that we also need to know about implications of changing numbers of children among those who are parents. Gender of children, particularly the availability of a daughter, is also potentially important and is associated with family size as the larger the family the greater the chance of having at least one daughter. In this article, we use data from the English Longitudinal Study of Ageing (ELSA) to analyze associations between number of living natural children, and in analyses of a subsample of parents, availability of a daughter, with two indicators of social support for older people, frequent face-toface contact and receipt of instrumental help, both of which may be regarded as indicators of intergenerational solidarity (Silverstein & Bengtson, 1997). We also investigate whether social contacts at one time point predict subsequent receipt of instrumental support as suggested in conceptual models, which view social contacts as an indicator of the social network from which social support, including instrumental help, may be drawn (Berkman, Glass, Brissette, & Seeman, 2000). A third important aim of the article is to investigate whether those with no or few children “compensate” through a greater propensity to meet and receive help from friends and relatives other than children.
