Abstract
The rapid aging process and slowdown of fertility have become growing focal points in the international, national and local agendas. In this scenario, intergenerational solidarity is a bet on the recognition of youngsters and the elderly from their political constitution. Likewise, it presents a possibility of dialogue between generations to build inclusive spaces that reveal that aging has economic and political implications but also political implications. The present article uses the terms social sustainability and intergenerational solidarity as essential elements for the process of political training of young people and the elderly. It shows the reflections taken from the intervention process in social work and, based on this, it also shows several contributions and questions in the field of the application of youth and aging social policies.
