The fertility decline associated pure energy jeans with economic development has been attributed to a host of interrelated causes including the rising costs of children with industrialization, and shifts in family structure.One hypothesis is that kin may impart more pro-natal information within their networks than non-kin, and that this effect may be exacerbated in networks with high kin-density where greater social conformity would be expected.In this study, we tested these ideas using large personal networks (25 associates of the respondent) collected from a sample of Dutch women (N = 706).Kin (parents) were perceived to exert slightly more social pressure to have children than non-kin, although dense networks were not associated with greater pressure.

In contrast, women reported talking to friends about having children to a greater extent than kin, although greater kin-density in the network increased the likelihood of women reporting that they could talk to kin about having children.Both consanguineal and affinal kin could be asked to help with child-care to a greater extent than friends and other non-kin.Overall, sofia barclay sexy there was mixed evidence that kin were more likely to offer pro-natal information than non-kin, and better evidence to suggest that kin were considered to be a better source of child-care support.
