The configurational studies of this special issue trace complex patterns of interdependencies existing among family members and beyond households. They focus on the functional connections among spouses, children, siblings, and other relatives living in a variety of households. The main goal of this special issue is to reveal how some key decisions and exchanges occurring in family dyads, such as the marital and parent–child dyads, are embedded within a larger set of family and interpersonal exchanges that constitute configurations of their own in a variety of contexts.

Most research on financial inter vivos transfers from older parents to their family members is focused on the giver–receiver dyad, usually between an older parent and an adult child. This study aimed to investigate older adults' financial support beyond this level of intergenerational dyads using an egocentric network perspective (i.e., the configurational approach). Data were from a sample of 2,991 older adults (aged 65 and older) from the Vivre/Leben/Vivere study, a large survey addressing family life and health conditions of older people in Switzerland. We used Wald tests and regression analyses to identify how financial transfers are related to family network properties in later life. Findings showed that older parents' propensity to provide financial support is associated with the density of practical help exchanges within the family (mainly for men) and with the position (mainly for women) and the role they play within their family configuration.

This study aims to determine the role played by the personal networks of mothers aged 25–40 in Bamako (Mali) in their recourse to prenatal care. Although education and household's economic situation remain important, our research shows that personal network matters in two ways. Prenatal follow-up is more adequate in small, dense, less centralized networks, a structure known to generating a higher level of bonding social capital and mutual support. Yet, the composition of networks is also important: those comprising the husband and neighbors/friends—without other family members—are associated with better prenatal care. In these more open networks, women are probably less subject to traditional social control. An unexpected outcome is that material support does not play a significative role; this may indicate that more specific measures are needed to identify the type of support useful, or that, in this context, normative aspects are more important.

As exchanges of instrumental support between kin and non-kin remain essential to buffer the impact of critical life events, we consider the characteristics of personal configurations that may enhance or hinder them. Personal configurations vary in terms of their composition and two aspects of their structure: density and centrality. These dimensions are investigated to uncover whether they influence the type of instrumental support being exchanged (financial, material, and care) and the likelihood of their being reciprocal. Drawing on a representative sample of individuals living in Switzerland, results show that overall instrumental support is present in all personal configurations irrespective of their composition, but financial support is more prevalent in configurations based on parent–adult child relationships. Furthermore, configuration structures characterized by density of emotional support are positively associated with giving care support and with reciprocity, while those characterized by density of conflict are associated with giving less instrumental support overall.

Family solidarities remain strong in African societies. In Ouagadougou, transfers within extended family networks provide an omnipresent means for coping with life's difficulties, and the desired number of children remains relatively high. The role of family networks in maintaining high fertility is rarely studied however for lack of data in conventional demographic surveys. This study uses original retrospective data and logistic regression methods to explore the role of the extended family's social capital in shaping women's desire for children in Ouagadougou. Results show that women belong to three types of family networks: (1) women who belong to large family networks on both her own and her husband's side and who maintain a moderate number of close relations with their own relatives; (2) women who also belong to large family networks on both their and their husband's sides but who maintain a greater number of close relations with their own blood relatives; (3) unmarried women with relatives only on their side and numerous close relations with their family. Support for children's schooling comes more often from women's relatives in networks type 2 and 3, and from husbands' relatives in network type 1. Support for children's schooling increases with the level of economic resources in family networks (proxied by the presence of a public employee), in all network types. Women in type 2 networks (centered on women's relatives) are more likely to want additional children compared to women in type 1 networks (centered on their husband's relatives), after controlling for economic resources in networks. This result suggests that practical support provided by family members could play a role, on top of economic support, in encouraging high fertility in Ouagadougou.
