This article analyzes family transformations resulting from the impact of social welfare policies and modernization in Guadeloupe, an island in the French Caribbean. The analysis is taken from a study of three-generational families in which a ''pivot'' member between 49 and 53 years of age, one parent, and one adult child were interviewed. The study, combining both quantitative and qualitative methods, concerns the forms of cultural, domestic, and economic exchanges between the generations, in addition to the various social welfare allowances received by the members of the families who were interviewed. The results show the complementarity between public and family forms of support. They also show how social welfare benefits have transformed the respective social status of different generations, the functioning of family solidarity, and the ways that poverty is being fought.
