Social design is an interdisciplinary academic concept, research field, and methodological approach that applies design principles and processes to understand, address, and transform complex social issues and systems. It investigates the dynamics of human behavior, community needs, and societal structures to co-create interventions aimed at fostering positive, equitable, and sustainable social change. Characterized by its participatory nature, contextual sensitivity, and focus on systemic impact, social design seeks to move beyond conventional problem-solving to empower communities, enhance well-being, and contribute to social justice.
