The diversification of caregiving arrangements in European societies has drawn attention to the factors that condition the use of care by older people. Social and family relations appear as a key factor, mainly to be related to the availability and accessibility to potential informal caregivers. Recent studies evidenced that geographical proximity and a larger social network increase the probability of receiving informal support in old age. However, the ways in which interpersonal relationships are associated with the use of formal care, as well as the cross-country variability of this association, have been barely explored. Using a sample of 37,708 individuals aged 65 and over from Wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE), this study examines to what extent the characteristics of older people's social networks predict the use of three types of home care; formal, informal, or combined, exploring the cross-European convergences and divergences. Binomial logistic regressions are conducted to compare four macro-regions in continental Europe (northern countries: Denmark and Sweden; western countries: Austria, Belgium, France, Germany, Switzerland, and Luxembourg; southern countries: Italy, Spain, Greece, and Portugal; and eastern countries: Poland, Czech Republic, Slovenia, Estonia, and Croatia). The structure, availability, and accessibility to the members of the social network are the major predictors of the receipt of informal care everywhere. Regional divergences are observed regarding to formal care, alone or combined with informal caregivers.
