Objectives: This article proposes an intervention from the field of social sciences to improve the knowledge of informal caregivers about care for the elderly. Methods: We analyze the social and cultural relationships that support the informal care culture in Spain. Some of the most important factors that are an obstacle to the professionalization of the sector are presented. Findings: The profiles of the informal caregivers are established, highlighting that most of them are women, whether they are family members or not. Furthermore, we find a prominent role of immigrant women in the non-professional care sector. We also analyzed the different relationships that groups related to informal care of the elderly have with technologies, highlighting mobile phones and instant messaging applications. Conclusions: With this result, we proposed the public policies of care for the elderly to contemplate training actions transmitted through the mobile phone and messaging applications.
