This article analyses the dynamics of family solidarity in Spain. The existing literature so far has defined the Spanish caring model as familistic due to the primacy of the family in the protection of dependants. However, this article shows that recent data on Spaniards' preferences concerning the care of their family dependents might question the sustainability of the bases of such model. This is consistent with the results of the OASIS Project, according to which societal changes may be leading to family care becoming less duty-driven and more dependent on personal affection and attachment.
