The World Happiness Report is released annually by the Sustainable Development Solutions Network (SDSN) with support from the United Nations. It ranks countries based on citizens’ self-reported life satisfaction. The key parameters used include income levels, social support, healthy life expectancy, freedom to make life choices, generosity, and perceptions of corruption. The report provides insights into how social, economic, and governance factors influence well-being. It is widely used to understand quality of life and to guide governments in improving public policies focused on mental health and social cohesion.
